Efficient and realistic simulation of composite bolted joints is absolutely necessary in fully realizing the
benefits of composite materials to build lighter and more capable aircraft. Various techniques for efficient modeling of bolted joints have been investigated in recent publications – these techniques either use layered shell elements to represent the laminates or large numbers of three-dimensional solid elements by explicitly meshing each layer of the laminate.

This whitepaper will present a computationally efficient method for modeling thick composite bolted joints to aid in aircraft structures analysis.

See how the modeling strategy identifies the joint parameters to accurately capture load distributions in composite joints. Also learn how the MultiContinuum Theory (MCT) damage model is utilized as part of the modeling strategy to extract separate failure predictions for the fibers and epoxy matrices throughout the composite joints.
