A three-dimensional finite element model of the joint has been developed. The model has been used to predict the stress field of the laminate in the joint area, assuming homogeneity and linear behavior of the material. The modeled geometry is a T-bolt that joins a coupon of glass fiber–epoxy and a block of steel. The results obtained from the model have been verified experimentally using both e...
