Abstract:
In finite elast ic deformation, the direction and the density of the boundary force can great ly change w ith the deformat ion of the elast ic body . As for finite elast ic deformaion body, the inf luence of deformation on the boundary force should be considered in the nonlinear finite element analysis. The analytical expression of incremental force act ing on the boundary of the half space under finite deformat ion is obtained and tw o kinds of boundary forces are disussed in detail.
