WebThis methodology is based on micromechanics and the classical laminate theory. The methodology predicts a complete set of thermal, hygral and mechanical properties of plain woven composites, generates necessary data for use in a finite element structural analysis, and predicts stresses all the way from the laminate to the constituent level. WebExperimental results show that mid-plane symmetric composite laminates of semi-cylindrical, curved geometry warp during manufacture and continue to change shape with changing temperature throughout their service life. A mathematical model is presented which predicts the observed shape change and yields results which compare closely with …

http://nwp.engr.udel.edu/ccm/CDS/ThinPlateClassicalLaminateModel.html WebClassical laminate theory, the same theory that is used to distribute the loads and moments into each ply for the ply-by-ply stress analysis approach, assumes that the strain in the laminate maintains a smooth, linear distribution. There is a necessity for the laminate to operate as a coherent cross-section when reacting load.
