The purpose of our study is to understand the shear performance of layered CFRP laminates at wide temperature range changed from room temperature to cryogenic temperature. Analytical evaluations of the v-notched specimens (Iosipescu shear test) to determine the in plane and out-of-plane (interlaminar) shear properties (modulus and strength) of layered CFRP laminates have been conducted through the finite element modeling. Analytical results were utilized to examine how closely the test would meet the requirement of an ideal shear test that there should be pure and uniform stress and strain distributions in the test region. Different correction factors of the v-notch shear specimens for in plane and out-of-plane shear property determinations are obtained respectively and will be used to modify the experimental results in the coming study.
