The out-of-plane shear response of thick, unidirectional and crossply, AS4/3501-6 and S2 glass/3501-6 laminates was investigated theoretically and experimentally. The specimens considered were of the V-notched beam (Iosipescu) configuration. Strains were monitored in the specimen test sections using conventional strain gages, moire interferometry, and new full section strain gages. Crossply laminates exhibited a fairly uniform strain distribution away from the notches resulting in agreement of initial moduli obtained through all ...
