S.P. Tymoshenko of the National Academy of Sciences of Ukraine popup.description2  Techniques are developed for determining the fracture characteristics of elastic and viscoelastic composites with a collinear crack system under the distributed loads. In particular, a technique is given for determining the critical load level using a crack model with a nonlinear interaction cohesive zone for the structural elements with a system of collinear cracks, as well as a technique of the stress field determination for the finite structural elements with collinear cracks. Obtained are results on the influence of the mutual location of collinear cracks on the crack opening in the case of edge cracks in the elastic structural element. An algorithm is developed for studying the growth of collinear cracks in a structural element with viscoelastic properties using the finite element method.
