形状记忆合金薄板低速冲击载荷下热力耦合行为分析
Experiment and simulation of thermomechanical coupled behavior of SMA under low velocity impact
摘要
Abstract
The thermomechanical coupled behaviour of shape memory alloy (SMA) sheet under low velocity impact loading was investigated. Based on the SMA thermomechanical constitutive model, the impact response of SMA sheet was numerically simulated in software to explore the characteristics of SMA thermomechanical coupled behaviour under impact load.The numerical simulation results are in good agreement with the experimental data, which effectively characterizes the thermomechanical coupled behaviour, such as deformation, phase transformation, dissipation and temperature change, etc. during the impact of SMA sheet.关键词
