Micromechanics of fibre glass composites at elevated temperatures

The micromechanical assessment of ultimate response of moulded bre glass (MFG) composites used in structural engineering and acting at elevated temperatures is treated in the present paper. The advanced crystal simulation model of the MFG-material at elevated temperatures, based on Washizu’s variational principle, is presented. The numerical treatment of non-linear problems possibly appearing is made using the updated Lagrangian formulation of motion. Each step of iteration approaches the solution of the linear problem and the feasibility of the parallel processing FETM-simulation approach is established. Some numerical and experimental results are presented in order to demonstrate the e ciency of procedures suggested
