# Youngs Modulus Study

Material stiffness and density is directly affected by the manufacturing process, especially in injection molding for plastic parts. In the industry, variations in Youngs Modulus,E-Modulus up to +/-30% are observed compared to supplier datasheets.

The Youngs Modulus Study Setup panel is as shown below.
The Youngs Modulus Study Setup panel allows you to perform following operations -
1. Select Parameter - a default selection list that shows the selected parameter. In this case, Youngs Modulus is the value.
2. Global Variation % - value entry field to provide the parameter variation range
3. Select All, Unselect All, Reverse Selection - parameter list selection options
4. Parameter list table - table listing the materials in the model
5. Add - to add a parameter variation study to the study table
6. Update - to update an existing study parameter
7. Parameter Variation Study table - a table listing the study variations created
