Research on Stability of E-Glass Fiber/Epoxy Composite Material Tube
Abstract:
This paper studies on the stability capacity of E-glass fiber reinforced polymer (GFRP) tubes under axial compression in order to get the formula, which can be applied to structure design. Firstly, on the basis of test data, finite element analysis is carried out and initial geometric imperfection is considered in the models. Then, it's proved that edge-failure criterion is suitable for stability analysis of GFRP slender components by comparison of results derived from several classic formulas. Finally, a modified Perry-Robertson stability formula is proposed so as to ascertain corresponding stability coefficients for GFRP tubes with different slenderness ratio.
