Mechanical Response of Porcine Liver Tissue under High Strain Rate Compression

Coupled experiment/finite element analysis on the mechanical response of porcine brain under high strain rates.

This paper presents a coupled experimental/modeling study of the mechanical response of porcine brain under high strain rate loading conditions. Essentially, the stress wave propagation through the brain tissue is quantified. A Split-Hopkinson Pressure Bar (SPHB) apparatus, using a polycarbonate (viscoelastic) striker bar was employed for inducing compression waves for strain rates ranging from...

High strain-rate behavior of ice under uniaxial compression

In the present study, a modified split Hopkinson pressure bar (SHPB) is employed to investigate the dynamic response of ice under uniaxial compression in the range of strain rates from 60 to 1400 s 1 and at initial test temperatures of 10 and 30 C. The compressive strength of ice shows positive strain-rate sensitivity over the range of strain rates employed; a slight influence of ice microstruc...

Mechanical Behavior of MTMoCr Under High Temperature and High Strain-rate

MTMoCr is a kind of Mo-Cr alloy cast iron often used to make automobile panel dies. To study high-speed machining process of automobile panel dies, the material’s elastic modulus and rupture critical values of MTMoCr at 20 -800 were studied based on the high temperature elongation test. The material’s stress-strain diagram at various temperatures set-points (20 -500 ) and various strain-rates (...

Mechanical Behavior of TWIP Steel in High Strain Rate Torsional Test

Advanced high strength steels (AHSS) have recently attracted great attention because of their superior mechanical properties. A modern group of these steels, known as twinning induced plasticity (TWIP) steels, shows a unique combination of strength and ductility even at high rates of strain. In order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...
