Abstract
The study considers numerical modelling and simulation of static processes, including progressive failure, for GFRP (glass fibre reinforced plastic) laminates, of a mixed sequence of laminas reinforced with E-glass plain weave fabric or E-glass mat. The laminate has been manufactured on polyester matrix. The purpose of the research is to determine the options/values, recommended in engineering calculations, of parameters for numerical modelling and simulation of static processes including failure for beam, plate and shell structures built of composites undertaken, using FE code MSC.Marc. The effective elastic and strength constants of homogeneous laminas have been determined experimentally at room temperature according to standard procedures. The 3-point bending test of composite beams has been conducted experimentally and simulated numerically. The experimental validation of numerical modelling and simulation of the bending test is positive in both the quasi-linear and the progressive failure zones.
