The DLST specimens are constructed by bonding carbon fiber reinforced polymer (CFRP) to concrete prisms with epoxy adhesive. FEM was performed to investigate the effects of the CFRP thickness, overlap length, and temperature on the performance of the graphite/epoxy composite/concrete interface. Results indicate that the shear modulus has the greatest influence on the overall behavior of the double lap-strap specimen. Analysis of the CFRP to concrete interface showed that the resulting stress distribution is dependent on CFRP stiffness and CFRP thickness. Temperature dependent Critical Strain Energy Release Rate Gcr of the interface is obtained using crack closer model of the delaminating composite and experimental results.
