Second-order work analyses, based on elasto-plastic models, have been frequently carried out leading to the result that failure may occur the limit yield condition is encountered. In this article, second-order work investigations are carried out with barodesy regarding standard element tests and finite element applications. In barodesy, it was shown-like in hypoplasticity and elasto-plasticity-that second-order work may vanish at stress states inside the critical limit surface. Read More
