Dynamic Deformation of Materials and Structures Under Explosive Loadingsice is the accompanying uniqueness — stability theory. The object of this paper is to review and illustrate this methodology for modeling nonlinear hysteretic materials and for analyzing the behavior under shock loadings of nonlinear media and structures embedded in such media.

Dislocation Configurations Due to Plate Impactty with closely spaced, long glide bands emanating from both front and rear surfaces. Comparatively short, widely spaced interior glide bands have lengths comparable to those predicted by applying the linear drag model of ultrasonic attenuation studies to the stress levels of the plate impact experiments.

Experimental Studies on the Behaviour of Dislocations in Copper at High Rates of Strainasurements of the flow stress in a strain rate range from 1 × 10. to 2.5 × 10. /sec and at 293°, 573° and 773° K. A sharp increase in the strain rate sensitivity which means a transition in the rate controlling mechanism appeared at a strain rate of about 1 × 10. /sec. The behaviour of dislocations in this transition range is discussed.

Computer Simulation of Dislocation Groups Dynamics Under Applied Constant Stress and Its Applicationapplication in mild steel. The theoretical results are in good agreement with the experimental data on the temperature and the applied stress dependences of yield delay time and on the temperature and the stress rate dependences of upper yield stress in the mild steel using the same parameters, respectively.

Calculation of Spall Damage Accumulation in Ductile Metals successfully interpreted in terms of existing spall criteria, indicating again the qualitative agreement of the new results with prior experience. These comparisons provide an indication of the range of validity of the simpler criteria.
