Abstract

This paper presents the study on the crack-tip behavior in fiber/metal laminates under static loading. The effect on the strain field due to the variation of layup and fiber/preimpregnated has been analyzed. The strain field has been measured using digital-image correlation and evaluated by comparing it with the strain field predicted with finite-element analysis, which provided information about the interlaminar shear mechanisms. In addition, the paper demonstrates the power of the digital-image correlation technique for in situ strain measurements, offering new insight into the damage mechanisms that prevail in fiber/metal laminates under static loading.
