Compressive Stress/Strain Curve Data dialog

This dialog is used to input the compressive stress/strain characteristics of the material in the first principal and second principal directions. This data, if present, is used for a Stress creep analysis.

To access this dialog, you must have selected a reactive molding process, with a thermoset material. Click (Home tab > Molding Process Setup panel > Process Settings), and click Next until you find a page with the Advanced options button. Click Advanced options, then click Edit associated with Molding material. Select the Mechanical Properties tab, check Single set of stress-strain curves, and click the Edit stress-strain data button. Check Different second principal properties (tranversely isotropic), and click the Edit stress-strain data button. Check Different compression properties, and click the Edit stress-strain data button.

Dialog element	Explanation
First principal compressive stress-strain curve	Curve type If you have a large number of datapoints, select the multi-linear option. Multi-linear Curvilinear with slope continuity at the elastic limit Curvilinear without slope continuity at the elastic limit Failure strain Enter a number between 1 and 5.
Compressive stress-strain curve data (1st principal direction)	This section is for the 1st principal direction. You will have acquired this information from experimental data.
Second principal compressive stress-strain curve	Curve type If you have a large number of datapoints, select the multi-linear option. Multi-linear Curvilinear with slope continuity at the elastic limit Curvilinear without slope continuity at the elastic limit Failure strain Enter a number between 1 and 5.
Compressive stress-strain curve data (2nd principal direction)	This section is for the 2nd principal direction. You will have acquired this information from experimental data.
