II.4.7 Laminate load response for a simple loading

The calculation of the laminate response to a specified loading is always done in two steps:

1.

The laminate load response is calculated for a specific loading. This calculation is used to estimate laminate in-plane forces, bending moments, average strains, curvature, temperature variations... Also layered results are calculated if required. (See description of method “calcResponse” in section II.4.7.1.)

All these results are stored in the ClaLam object and remembered until the next calculation is performed.

2.

Then, the laminate can be “interrogated” to obtain a restitution of stored results, or the calculation of new results from the information stored since the last calculation. (See the methods described in sections II.4.7.2, II.4.7.3 and II.4.7.5.)

This way of working allows at the same time much flexibility in the recovery of results at an acceptable computational cost.

The different calculated results retrieved from the ClaLam object are expressed in the units system associated to laminate object. This means that even if the loading units or the material units differ from laminate units, FeResPost performs the conversions needed to obtain stresses, forces, moments and other results in the units system associated to laminate.
