Spall study in mild steel
Article Abstract:
A mathematical model was developed to examine the effect of inertial, thermal and material rate sensitivity on the thermal-viscoplastic solid's void growth under a high strain rate. A numerical analysis of the model showed that inertial, thermal and rate-sensitive effects greatly influence the void growth in porous ductile materials at high strain. The processes of one and two dimensional spallation in mild steel were successfully simulated when the model is incorporated in two-dimensional Lagrangian finite-difference computer dynamic code.

Modeling and identification of elastic-plastic systems using the distributed-element method
Article Abstract:
A method for distributed-element modeling was tested on several biaxial tension-torsion applications to determine its validity in modeling and identification of elastic-plastic systems. The distributed-element model features the invariant characteristics of the related yield surfaces. Results have shown that the modeling method does not need any additional kinematic hardening rules to effectively account for the multi-axial Bauschinger effect.
