【摘要】 本文应用小变形叠加到大变形上的分析方法,考察了表面受常静水载荷作用下,谐和弹性半无限体的表面平面应变失稳问题。分析表明,对于标准材料情形,压缩方向的临界主伸缩比随静水载荷值的增大而减小,相应的临界载荷则随之增大。更多还原

【Abstract】 The plane-strain buckling of a harmonic halfspace, subjected to a hydrostatic loading on its surface, istreated by using a small-deformation-superposed-on-large-def-ormation analysis. For a standard material, it is shown thatthe critical stretch ratio in the direction of compression decr-eases and the corresponding critical buckling load increases,asthe hydrostatic loading increases.更多还原
