Crack initiation in a stiffened plate
M. V. Mir-Salim-zadeh Azerbaijan Technical University, Baku, AZ1129, Azerbaijan
Abstract:
The fracture mechanics problem of crack initiation in a stiffened plate is considered. The crack nucleus is modeled by a prefracture zone with bonds between the crack faces, which is treated as a region of weakened interparticle bonds of the material. The boundary-value problem of the equilibrium of a stiffened plate with a crack nucleus reduces to a nonlinear singular integrodifferential equation with a Cauchy type kernel. The strains in the crack initiation zone are found by solving this equation. The case of the stress state of the plate with a periodic system of prefracture zones is considered.
Keywords:
prefracture zone, adhesion forces, strains in interfacial bonds, crack initiation.
