II.4.1 Class Methods

One shows in section II.1.6 that two arbitrary parameters ${\mu }_x$ and ${\mu }_y$ define the relations between $x$ and $y$ partial derivatives of laminate bending moment components and out-of-plane shear forces when the $\left({\mu }_x,{\mu }_y\right)$” approach is adopted. The default values of these parameters are ${\mu }_x={\mu }_y=1$. Two Class Methods allow the manipulation of these parameters:

• “setMuxMuy” has two Real parameters and is used to set the values of ${\mu }_x$ and ${\mu }_y$ respectively.
• “getMuxMuy” returns an Array of two Real objects corresponding to ${\mu }_x$ and ${\mu }_y$ respectively.

As these methods are Class methods, the modification of ${\mu }_x$ or ${\mu }_y$ affects all the laminates defined in all the CLA databases.

Similarly, one methods allows to select the laminate out-of-plane shear calculation approach. The method is called “setOopsApproach” and has onesString parameter that has three acceptable values: “Standard”, “UncoupledXY” and “InShearLoadingAxes”. These values correspond to the calculation approaches discussed in section II.1.6.5. “Standard” is the default approach. Method “getOopsApproach” allows to check which approach has been selected. Here again, “setOopsApproach” affects all the laminates defined in all the CLA databases.

“setMuxMuy” and “setOopsApproach” should be used (if used) only once before they creation of the first laminate by FeResPost. Otherwise unexpected behaviour is possible. Indeed, intermediate matrices are stored in C++ laminate objects and the modification of the calculation approach after laminates have been created may lead to mixture of matrices and vectors obtained via different approaches.
