The laminate is assumed to be under thermal loading. Jk-integral is formulated by using the constitutive relations of plane orthotropic thermoelasticity. Developed domain independent form of the Jk-integral is then integrated into the general purpose finite element analysis software ANSYS. Numerical results are generated so as to assess the influence of variable fiber spacing on mode I and II stress intensity factors, energy release rate, and T-stress. For verification, some of the results are compared to those obtained using displacement correlation technique (DCT).}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {11}, number = {3}, year = {2017}, pages = {512 - 519}, ee = {https://publications.waset.org/pdf/10006541}, url = {https://publications.waset.org/vol/123}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 123, 2017}, }
