Coupled Thermodynamically Consistent Thermo-mechanical Model of Silica Glass Subjected to Hyperveloc
Silica-based glass may possess paradoxically high resistance to hypervelocity impact due to the experimentally observed phase change...
Multiscale modeling of reinforced concrete structures
A novel multiscale approach for analysis of reinforced concrete structural elements that overcomes two major hurdles in utilization of...
Is an additive decomposition of a rate of deformation and objective stress rates passé?
A half a century old idea of decomposing the rate of deformation into elastic and plastic parts is critically examined. We show that even...
Computational Continua - Multiscale Framework
Computational continua is a higher order continuum formulation. From a theoretical point of view, the computational continua is endowed...
Stochastic Multiscale Forward and Inverse Solver
An adaptive variant of the measure-theoretic approach (MTA) for stochastic characterization of micromechanical properties based on the...
Adaptive Delamination by S-method
A methodology aimed at addressing computational complexity of analyzing delamination in large structural components made of laminated...
Computational Certification under Limited Experiments
A computational certification framework under limited experimental data is developed. By this approach, a high fidelity model (HFM) is...
Femur Fracture
Two multiscale approaches for fracture analysis of full scale femur are developed. The two approaches are the reduced order...
MultiSPH-Permeability in a Multi-porosity Porous Medium
An upscaling approach for multi-porosity media is developed and demonstrated on a three-scale porous medium. The three-scale porous...
FEM-DEM coupling
A three-dimensional nonlocal multiscale discrete-continuum model has been developed for modeling mechanical behavior of granular...
