<p>In this study, we propose a credibility factor to evaluate the credibility of material model and its parameters calibrated from material tests, based on the concept of credibility evaluation of simulation models presented in ASME V&V-40. In solid simulations, it is common to identify material parameters so as to reproduce the response obtained in material tests, so the reproducibility of this response alone is not sufficient to evaluate the credibility of the simulation model. This paper proposes a new credibility factor and its gradations, checking the reproducibility of responses that are not used for parameter identification. Using 4-point bending tests on plastic materials and wood as examples, we will show the difference in credibility evaluation for calibrated model that only identify parameters and one that confirm the reproducibility of other responses.</p>

Effects of Microscopic Anisotropy on Macroscopic Damage Propagation

Authorship：Last author Language：Japanese Publishing type：Research paper (scientific journal) Publisher：National Committee for IUTAM Joint Work
<p>In this paper, the anisotropic nature of micro structures in multi-scale modeling, are studied in the context of their macroscopic damage propagation. Generally speaking, any assumed micro structures (RVE’s) in FE2 simulations give macroscopically anisotropic responses, and it is necessary to evaluate their effects on macroscopic strength for ductile failures. Not only by changing the macroscopic stress states, but also the gap between the stress axis and microscopic axis for anisotropy, the changes in macroscopic responses against a certain stress states would be evaluated via conventional FE2 simulations.</p>

Thermal-Structural Simulation for Sintering Ceramics

NCTAM papers, National Congress of Theoretical and Applied Mechanics, Japan 66 ( 0 ) 21 2022
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：National Committee for IUTAM Joint Work
<p>In this paper, a simple simulation strategy for sintering ceramics is proposed as thermal-structural problems. Assuming that thermal and mechanical deformations are independent, the total deformation is decomposed into thermal and mechanical component, and they are also decomposed into reversible and irreversible components. For the thermal irreversible strain, Master Sintering Curve is employed, and Peric's viscoplasticity model is used for the mechanical irreversible strain. The model is introduced into ANSYS, thermal-structural analysis with User Programmable Feature (UPF). The simulation is validated by comparing with sintering experiment with/without external axial compression load.</p>

<p>The simultaneously iterative procedure for elastic-plastic boundary value problems proposed by the authors is extended to elastoplastic problems under plane stress state. The authors define a coupled problem of the equilibrium equation, the yield equation, and the plane stress condition at every material points, and develop a numerical procedure based on the block Newton method to solve them with simultaneous linearization. In the proposed block Newton method, the tangent moduli can be constructed algebraically by eliminating the internal variables, which are also updated algebraically without local iterative calculation. In addition, the residuals of yield criterion and plane stress state are incorporated into the linearized equilibrium equation. Hence, the proposed procedure enables us to decrease the residuals in the coupled boundary value problems simultaneously. Some numerical examples illustrate the validity and the effectiveness of the procedures under plane stress state with material nonlinearity.</p>

In the finite element analysis, it is important to evaluate the local behavior at the portion where the thickness is discontinuous or near the corners. If such structure is discretized with structural elements, the numerical results are often unreliable, because the plane stress condition is assumed in the transverse direction and the incompressibility could not be considered appropriately. Thus, the authors proposed that the effective procedure of discretizing the model is to connect shell and solid elements properly by using Nitsche's method.<br>When the different types of elements are connected at the boundary including corners, the stiffness near such boundary may become larger than that of the model discretized with only one type of element. Thus, the authors propose the approach to avoid this problem by improving the mesh geometry near the boundary.<br>The proposed procedure can be applied to the elastoplastic problems, but it is necessary to divide the domain so that the plastic region does not progress on the connecting interface. This is because the numerical calculation becomes unstable due to the disorder of the stress state when discontinuous stress state is connected.<br>This paper presents a numerical procedure for connecting shell and solid elements in elastoplastic problems. In the proposed approach, shell and solid elements can be coupled with reasonable deformation near the connecting interface, only when the plastic range is not included on the connecting interface.

<p>Steel materials typified by carbon steel are one of the important materials of social infrastructure. When handling these materials in numerical simulation, they are generally modeled as homogeneous continuum. This is because microscopic structures having various orientations are randomly combined, and as macroscopically can be considered as an isotropic body as a result. On the other hand, each such microscopic structure has a complicated structure. The microscopic structure of steel, in particular the kinematic behavior of cementite, is closely related to the ductile fracture of steel materials. That is, cementite in the steel material cracks during loading, and the void formed in the cracked region spreads, eventually leading to ductile fracture. When considering this series of phenomena as the progress of damage inside the material, it is interesting to see how the damage progresses. In the concept of continuum damage mechanics, not only general variables used for description of deformation, but also new internal variables with unique relationship with internal damage process are introduced to express damage inside the material. Alternatively, using multi-scale analysis based on homogenization method, it is possible to reflect the mechanical response of the microscopic structure as the material property of the macroscopic structure. By using this method, we can express internal damage of the material without preparing new variables representing damage. In this research, we focus on the growth behavior of the voids in the microstructure of the carbon steel after voids are generated, and propose a simple model that characterizes the growth phenomenon. Then, using this model, we perform micro and macro structure coupled analysis based on homogenization method.</p>

Ductile fracture simulation under multi-axial loading

<p>In this paper, ductile fracture simulation under the multiaxial loading is examined. Ductility of the material is considered by damage model, moreover, crack propagation is described by the finite cover method. Predicting the crack propagation phenomena about the metal material is necessary for the engineering field. Finite element method (FEM) is widely used to predict the metalworking and fracture process involves necking, crack, and failure. However, FEM is not good at predicting crack propagation. The generalized finite element method is good at describing discontinuous field like a fracture. Finite cover method(FCM), which defines the multiple covers, is one of the candidates to describe the discontinuous deformation. Moreover, a lot of constitutive equation has devised in order to deal with complex material behavior. Though there are many material constants, they sometimes have no physical meaning. In this study, a simplified Lemaitre model with FCM is employed to crack propagation simulation under multi-axial loading by applying different combinations of normal and transverse loads to the model. Some respective examples show the result of crack propagation and examine the effect of the multi-axial loading.</p>
