The subject undertaken in the study is a glass (fibre) – polyester (matrix) layered composite, of the mixed sequence, composed alternately of laminas reinforced with E-glass plain weave fabric (WR600) and E-glass mat (CSM450). The laminate is manufactured on Polimal 104 polyester matrix. The aim of the study is to determine the options/values of parameters for numerical modelling and simulation of static processes in shell structures made of glass-polyester composites undertaken, in MSC.Marc system, recommended in engineering calculations. The effective elastic and strength constants of homogeneous laminas have been determined experimentally according to the standard procedures. The bending test of composite beams has been conducted experimentally and simulated numerically. Numerical investigations have been focused on selection of options/values of the numerical modelling and simulation parameters. The experimental verification of numerical modelling of the bending test is positive in both the quasi-linear range and in the catastrophic – progressive failure zone.
