Analysis of no-tension structures under monotonic loading through an energy-based method
The collapse of 2D no-tension solids is dealt with as a set of energy-based analyses. An equivalent orthotropic material recovers the strain energy of the isotropic hyper-elastic body. The load history is not needed to perform analyses under a given load. The collapse load is computed with no a priori assumption on the failure mechanism. The numerical solution is in full agreement with solutions given by limit analysis.
