No-Tension Boundary Elements

Part of the Lecture Notes in Engineering book series (LNENG, volume 4)


The boundary element equations presented in previous chapters are employed here to solve problems concerned with the theory of no-tension materials. The no-tension criterion appears to be one of the first departures from linear elastic theory used to model rock behaviour. In order to justify the choice of this criterion some aspects of rocks and rock masses are discussed, and the inability of these materials to sustain tensile stresses is emphasized in practical problems. The solution technique to be presented is achieved by an iterative process which consists of computing at each step an initial stress field to compensate the tensile stresses. The no-tension solution is shown to be obtained assuming a non-path dependent behaviour, therefore does not require any incremental process. An alternative solution considering path dependent behaviour is also presented.
