Abstract

Abstract

Stress analysis for an infinite strip weakened by periodic cracks is studied. The cracks were assumed in a horizontal position, and the strip is applied by tension "p" in y-direction. The boundary value problem can be reduced into a complex mixed one. It is found that the EEVM (eigen-function expansion variational method) is efficient to solve the problem. The stress intensity factor at the crack tip and the T-stress were evaluated. From the deformation response under tension the cracked strip can be equivalent to an orthotropic strip without cracks. The elastic properties in the equivalent orthotropic strip were also investigated. Finally, numerical examples and results were given.
- eigenfunction expansion variational method,
- periodic crack,
- stress intensity factor,
- T-stress
