| Abstract: | The visco-elastic problem for a special deformable body, growing body, is investigated. Based on the moving grid, the time-varying element model and corresponding numerical method are developed to solve the time-varying problem. As numerical examples, the time histories of stress and strain are calculated for a pile with increasing height and for a thick-walled cylinder with decreasing inner diameter. |
