Elastic and Elastoplastic Contact Analysis: Using Boundary Elements and Mathematical ProgrammingWIT Press, 2005 - Počet stran: 121 Presents a general elastic and elastoplastic analysis method for the treatment of two- and three-dimensional contact problems between two deformable bodies undergoing small displacements with and without friction. The author's approach uses the Boundary Element Method (BEM) and Mathematical Programming (MP). |
