Presented is a constitutive framework for modeling the dynamic response of polycrystalline microstructures, posed in a thermodynamically consistent manner and accounting for finite deformation, strain rate dependence of flow stress, thermal softening, thermal expansion, heat conduction, and thermoelastic coupling. Assumptions of linear and square-root dependencies, respectively, of the stored e...

Due to excellent thermo-mechanical properties, tungsten (W) is considered as a promising divertor material in ITER, full divertor in JET, first wall in DEMO and ASDEX Upgrade. During plasma disruptions and ELMs the W material can be severely damaged because of macroscopic melt losses resulting in short lifetime and plasma contamination. Therefore, understanding the underlying forces and physica...

The Rajendran-Grove (RG) ceramic damage model is a three-dimensional internal variable based constitutive model for ceramic materials, with the considerations of micro-crack extension and void collapse. In the present paper, the RG ceramic model is implemented into the newly developed computational framework based on the Meshless Local Petrov-Galerkin (MLPG) method, for solving high-speed impac...

In this paper, research on AI based modeling technique to optimize development of new alloys with necessitated improvements in properties and chemical mixture over existing alloys as per functional requirements of product is done. The current research work novels AI in lieu of predictions to establish association between material and product customary. Advanced computational simulation techniqu...

Understanding the mechanisms of injury might prove useful in assisting the development of methods for the management and mitigation of traumatic brain injury (TBI). Computational head models can provide valuable insight into the multi-length-scale complexity associated with the primary nature of diffuse axonal injury. It involves understanding how the trauma to the head (at the centimeter lengt...

BRDFLab is a framework for modeling BRDFs intended for people working on representing, measuring and simulating material reflection. We describe the different functionalities provided by BRDFLab, which include the creation, inspection, fitting, and rendering of different types of BRDFs. We also show several examples of applications and describe how to easily expand its functionalities.
