Strength prediction of composite single lap joints using the critical longitudinal strain criterion and a meshless method

This work aims to test a meshless method, the Radial Point Interpolation Method (RPIM), in a multi material structure where the composite substrates are treated as an anisotropic material, and the adhesive as an isotropic material. The strength prediction is accomplished by the continuum mechanics-based Critical Longitudinal Strain (CLS) criterion. A stress and strain analysis showed that the RPIM can be used successfully in this type of...
