Stress-strain state of an elastic rectangular plate under dynamic load
Keywords:dynamic problem of elasticity, integral transform, loading rate
This paper considers a dynamic problem of elas-ticity for a rectangular plate under time-dependent tensile load, and uses it in modeling of transient stress-strain state of experimental samples under high-speed dynamic over-loading.
The solution of the problem is obtained using the integral transform approach. Based on this solution the paper studies the influence of loading rate on the transient stress in plate made of the aluminium alloy. It discusses the possibility of application in engineering analysis of a simpler one-dimensional model, which is also adopted.
