✦ Synopsis


A new concept of dropping damage boundary surface is proposed to evaluate the dropping damage of a critical component for a nonlinear packaging system, and a novel dynamical mathematical model is established to analyze the effect of three key coordinate parameters, i.e., the non-dimensional dropping shock velocity, the frequency parameter ratio and the defined system parameter, on dropping damage. An experiment was conducted to verify the theory prediction, showing good agreement.

In this paper, we consider a quasilinear elliptic system with both concave-convex nonlinearities and critical growth terms in bounded domains. The existence and multiplicity results of positive solutions are obtained by variational methods.
