A MUTI-SCALE CONSTITUTIVE MODEL AND ITS APPLICATIONSFOR GLASS FIBER COMPOSITES

Abstract

Abstract: Constitutive Model plays an important role in the design and analysis of composite structure, and one of the most widely used strength criteria is the Tsai-Wu criterion. In the Tsai-Wu criterion, the cross-term parameters are usually determined by double-axis test. Empirical values are often used to replace cross-term parameters, which affects the accuracy of the model. Based on the glass fiber reinforced composite material, this study establishes a multi-scale model. In order to determine the cross-term parameters, simulation is performed under the double-axis load condition. On this basis, a multi-scale model of glass fiber composite material is established, and the accuracy of the model is verified by three-point bending simulation and experiment. The results show that the calculation error is less than 5%. Finally, the established model is applied to the design and analysis of a glass fiber composite leaf spring, and the result meets the design requirements.

Key words: glass fiber, multi-scale simulation, leaf spring, lightweight, composites
