The initiation of a longitudinal shear crack (mode III fracture) in elastoplastic materials with the limiting strain is considered. The crack propagation criterion is formulated using a modified Leonov–Panasyuk–Dugdale model using an additional p

The initiation of a longitudinal shear crack (mode III fracture) in homogeneous structures and weld joints of elastoplastic materials with the limiting strain is considered. To obtain critical fracture parameters, a coupled (sufficient) fracture crit

A two-parameter (coupled) discrete-integral criterion of fracture is proposed. It can be used to construct fracture diagrams for compact specimens with sharp cracks. Curves separating the stress–crack length plane into three domains are plotted. Th

The paper concerns propagation of cracks in structures. The coupled fracture criterion is used when plotting diagrams of quasi-brittle failure of structures made of elastic-plastic material having ultimate strain. Diagrams of quasi-brittle fracture f

Critical stresses for quasi-brittle bimaterial with edge cracks have been obtained. Cracks along the plane interface of the bimaterial are simulated as bilateral cuts. The critical stresses correspond to necessary and sufficient fracture criteria and
