Damage Development in Static and Dynamic Deformations of Fiber-Reinforced Composite Plates
… finite element code to analyze coupled thermomechanical deformations of composites has been developed. It incorporates geometric nonlinearities, delamination between adjoining layers, and damage due to fiber breakage, fiber/matrix debonding, and matrix cracking. The three damage modes …

Multiscale Analysis of Failure in Heterogeneous Solids Under Dynamic Loading
Plane strain transient finite thermomechanical deformations of heat-conducting particulate composites comprised of circular tungsten particulates in nickel-iron matrix are analyzed using the finite element method to delineate the initiation and propagation of brittle/ductile failures by the nodal …

Effect of Material and Geometric Parameters on Deformations of a Dynamically loaded Prenotched Plate
We analyze plane strain thermomechanical deformations of a prenotched rectangular plate impacted on one side by a prismatic body of rectangular cross-section and moving parallel to axis of the notch. Both the plate and the projectile are made of the same material. Strain hardening, strain-rate …

Finite Element Analysis of Thermoviscoplastic Deformations of an Impact-Loaded Prenotched Plate
… problem corresponding to simple shearing deformations so that the computed effective stress vs. the effective plastic strain curves match closely with the experimental data of Marchand and Duffy who tested thin-walled HY-100 steel tubes in torsion. These four viscoplastic relations are …

Taylor Impact Test and Penetration of Reinforced Concrete Targets by Cylindrical Composite Rods
We use the three-dimensional finite element code DYNA3D to analyze two problems: (a) the normal impact of a cylindrical monolithic or composite rod against a smooth flat rigid target, (commonly known as the Taylor impact test), and (b) the penetration of composite and monolithic steel cylindrical …
