摘要: Abstract For perfect no-tension materials (NRT) the validity of local stability postulate Drucker, well known in plasticity, has been assumed so far and utilized to derive cracking laws, which relate strain states stress each other. On this base a finite-element (FE) model with suitable constitutive behaviour for single FE is presented. Classical approaches enforce laws at Gauss points FEs. In work it shown that taking into account strains, suitably modelled, over whole domain making use an energy approach lead general describing FE. The analysis masonry structures plane also presented prove efficiency such
