Analysis of Adiabatic Shear Banding in a Thick-Walled Steel Tube by the Finite Element Method
The initiation and propagation of adiabatic shear bands is analyzed numerically for an impulsively loaded thick-walled steel tube. A circumferential V-notch located at the outer surface of the center of the tube provides a stress concentration. The material is modeled as strain hardening, …

Strain Localization in Tungsten Heavy Alloys and Glassy Polymers
… places. Thus strains may localize into narrow bands at one or more places depending upon the microstructure of the alloy. We analyze the strain localization phenomenon during explosion and implosion of WHA hollow cylinders. We have developed a procedure to generate three-dimensional …

Multiscale Analysis of Failure in Heterogeneous Solids Under Dynamic Loading
… particulates strongly influences when and where adiabatic shear bands (ASB) initiate and their paths. Furthermore, an ASB initiates sooner in the composite than in either one of its constituents. We have studied the initiation and propagation of a brittle crack in a precracked plate deformed in …

Numerical Simulation of Adiabatic Shear Bands and Crack Propagation in Thermoviscoplastic Materials
… speeds. The formation and propagation of an adiabatic shear band (ASB) inplane strain tensile deformations is studied for eleven materials. The ASB is assumed to form when the maximum shear stress has been reduced to 80% of its peak value at a point and it is deforming plastically. The …
