Abstract:

A controlled cyclic loading system and stroboscopic light source was selected to analyze the in-plane loading of plates and frames. The controlled cyclic loading system and stroboscopic light source can be used effectively and economically to obtain good photographs with a conventional camera of dynamic isochromatic patterns in low- and high-modulus plates and frames except for the high-modulus embedded-polariscope models.
