Comparative study between 2D and 3D FEM techniques in single bolt, single lap, composite bolted joints for space structures
Two-dimensional and three-dimensional finite element models have been developed to study the effects of bolt-hole clearance on the mechanical behavior of bolted composites (graphite/epoxy) joints in space structures. The type of the studied joint was single bolt, single lap, and the geometry is a st...

| Summary: | Two-dimensional and three-dimensional finite element models have been developed to study the effects of bolt-hole clearance on the mechanical behavior of bolted composites (graphite/epoxy) joints in space structures. The type of the studied joint was single bolt, single lap, and the geometry is a standard type for these kind of composite joints space structures. In this study, two approaches, 2D (linear analysis) and 3D (nonlinear analysis) were developed and the results were compared to numerical and experiment results from literature. The contact between the parts affecting the accuracy and efficiency of the models is detailed. The model’s capability to predict the three-dimensional effects such as secondary bending and through-thickness variations of the stress and stain tensor fields is presented. |
