II.1.9 Accelerating the calculation of load response

In section II.1.8, one explained the different steps to solve the laminate load response equation, and estimate ply stresses and strains. The number of operations involved in these calculations is very important, and when repetitive calculation of laminate load response is done, the computation time can increase unacceptably. This is the case, for example, when laminate load response analysis is performed on loads extracted from finite element model results.

However, many operations described in section II.1.8 will be the same for each different loading. This means that these operations could be done only once for the different laminate loads considered in the analysis. We investigate in this section the possible accelerations of laminate load response analysis.
