LENGTH-SCALE EFFECT IN STABILITY PROBLEMS FOR MICRO-PERIODICALLY STIFFENED CYLINDRICAL SHELLS

摘要：

Thin linear-elastic cylindrical shells having a micro-periodic structure along one direction tangent to the shell midsurface (uniperiodic shells) are object of considerations.The aim of this paper is to investigate the effect of a periodicity cell size on the stationary stability of such shells.In order to take into account the length-scale effect in special stability problems,a new averaged non-asymptotic model of uniperiodic shells,proposed by Tomczyk in 2,is applied.In the framework of this model not only the fundamental classical critical forces but also the new additional higher-order critical forces depending on the period of heterogeneity will be derived and discussed
