This paper describes the experiments on the dynamic response of materials such as aluminum alloy, copper, stainless steel and porous stainless steel under pulsed electron beams heating. The experimental results show that nonporous material exhibits spallation fracture and woven-type porous material exhibits cross-crack" damage; but the felt-type porous material exhibits "convex deformation": the spattation damage belong to the dynamic ductile fracture: and there is a tendency that the threshold energy of convex...

In this research.the specimens of 270AI-Li alloy subjected to three different thermal-heated conditions are tested by different static and dynamic experimental method. Through comparision of the static and dynamic experimental results, it is shown that Al-Li alloyes have the unusual effects of inverted strain-rate sensitivity and properties of dynamic ductility. Furthermore, for the purpose of practical applications, the above mechanical behaviours of the Al-Li alloy are described and discussed theoretically...

In this research.the specimens of 270AI-Li alloy subjected to three different thermal-heated conditions are tested by different static and dynamic experimental method. Through comparision of the static and dynamic experimental results, it is shown that Al-Li alloyes have the unusual effects of inverted strain-rate sensitivity and properties of dynamic ductility. Furthermore, for the purpose of practical applications, the above mechanical behaviours of the Al-Li alloy are described and discussed theoretically by use of the no-yield visco-plastic model which was proposed by the authors. The theoretical calculated curves show consistency with the experimental very well.
