Analysis of Stress and Strain Uniformity of Muscle-Like Extra-Soft Viscoelastic Material in SHPB Experiment
肌肉类粘弹性超软材料SHPB实验的应力应变均匀性分析

Validity of SHPB test is based on assumption of the axial stress and strain uniformity within specimen,and is especially important for muscle-like viscoelastic extra-soft material.Dimensionless parameters influencing the stress and strain uniformity of viscoelastic material subjected to SHPB test were analyzed based on dimension analysis,and the influence of dimensionless parameters on the uniformity of viscoelastic material was investigated by using LS-DYNA numerical simulation.Results show that in order t...
