摘要：

An elastic-plastic fracturing solid with regular yield and fracturing surfaces in a quasi-static state of small deformation is considered, A pair of “dual” extremum theorems which reduce the boundary value rate problem to the optimization of convex quadratic forms subject to linear inequalities and equations is established. The validity in this field of classical extremum principles for elastic-plastic solids is also proved. © 1979, Taylor & Francis Group, LLC. All rights reserved.
