II.4.5 Other data

The reference temperature of a laminate is accessed with the two following methods:

• “clearAllowables” has no arguments and erases all the allowables stored in a ClaLam.
• “insertAllowables” is used to add material allowables. This method must be used if the calculation of failure indices or reserve factor is done using laminate allowables instead of ply materials allowables. (See section II.3.3 for more explanation on the use of this method.)
• “getDataAllowables” has no arguments and returns a Hash containing the data defining allowables. (See the corresponding method in ClaMat class section II.3.3.)
• “setRefT” has one Real argument and sets the reference temperature of the laminate.
• “getRefT” returns the reference temperature (a Real object).
• “setRefH” has one Real argument and sets the reference moisture of the laminate.
• “getRefH” returns the reference moisture (a Real object).
• “setLaminateIlss” has one Real argument and sets the value of laminate inter-laminar shear strength allowable at laminate level.
• “setAllPliesIlss” has one Real argument and sets the value of laminate inter-laminar shear strength allowable for all the plies defined in the ClaLam.

Note that an ILSS criterion is calculated, the allowables are always extracted from the laminate definition. When no ClaDb argument is provided for the calculation of the criterion, the laminate “ilss” allowable is used; when a ClaDb argument is provided, the ply “ilss” allowables are used. This means that the “ilss” allowable provided in ClaMat materials is never used.

Obviously, the different data inserted in, or retrieved from the ClaLam object should be consistent with the set of units attributed to the same object. This set of units can be attributed to the object after initialization of the data.
