Abstract: | Stress analysis for an infinite strip weakened by periodic cracks is studied. The cracks were assumed in a horizontal position,
and the strip was applied by tension “p” iny-direction. The boundary value problem can be reduced into a complex mixed one. It is found that the EEVM (eigenfunction expansion
variational method) is efficient to solve the problem. The stress intensity factor at the crack tip and theT-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.
