Impact Failure Mechanisms in Fiber-Reinforced Composite Platesbe a significant factor in the energy absorption at impact speeds below the speed required for perforation of the plate by a small rigid impactor. A linear relationship is found between impactor kinetic energy and total delamination area in this impact speed range (above a threshold speed) when the

Computer Simulation of Dislocation Groups Dynamics Under Applied Constant Stress and Its Applicationer simulation on dislocation groups dynamics..Based on this simulation and the previous one, yield model in bcc metals is proposed and the results are applied to the problem of the delay to the yield initiation under rapidly applied constant stress and of initial yield under constant rate of stress

Computer Modeling of Microscopic Failure Processes Under Dynamic Loadsof voids, cracks, or shear bands. We have constructed computational models describing these processes and have used these models to predict macroscopic failure behavior in many materials under compressive, tensile, and shear loading conditions. This paper reviews the microphenom-enology of dynamic f

Calculation of Spall Damage Accumulation in Ductile Metalsg problems of propagation of plane waves of uniaxial strain. Solutions for plate-impact problems covering the range of sample thickness and impact velocity normally encountered in experimental investigations are discussed and shown to be in qualitative accord with observation. Calculated results are

Crack Propagation in Plastics Due to Impactthyl methacrylate and polycarbonate. Stress wave passage was monitored by strain gages mounted on the specimens. A 24-frame Cranz-Schardin camera recorded crack position and the stress intensity factor at its tip, the latter by means of a shadowgraphic technique known as the method of caustics, deve

Loads and Crack Velocities During Dynamic Fracturehe initial slow crack growth and the strain rate dependent crack propagation velocity profiles, are presented in connection with the applied strain rates and temperatures. The newly devised velocity gauge method to measure the very initial slow crack growth in viscoelastic solids is also briefly des
