DETAILED 3D SIMULATION OF BOLTED PULTRUDED COMPOSITE CONNECTIONS

Abstract eng:
An experimental and analyitical study is carried out to investigate the response of bolted pultruded composite connections using nonlinear material and detailed 3D structural finite element (FE) models. A new 3D micromechanical model for the fiber reinforced plastic (FRP) pultruded composite material is used to generate the effective nonlinear response at each Gaussian material point within the 3D FE model. The constitutive model is calibrated by specifying the fiber and matrix elastic and nonlinear parameters. The fiber material is linear isotropic while the matrix is nonlinear plastic. The material parameters are determined from coupons taken from the pultruded beams. The effect of slip between the components and the bolts on the overall response of the connection is included by explicitly recognizing contact and friction between all the components. Pull tests are also performed in order to compare the prediction ability of the overall combined material and structural framework.
