Stress analyses are used to identify structural related problems, typically with the strength, stiffness, and life expectancy of plastic products.
The Stress analysis program performs isotropic and orthotropic stress analysis of normal or fiber-reinforced thermoplastic materials. Stress analysis for injection molding predicts actual molding stiffness. It analyzes a product for possible structural defects or failure points when the product is exposed to a load. In order to perform a Stress analysis, your study must contain:
Constraints must be carefully applied so that they are representative of the physical situation being modeled. By default, the six degrees of freedom of all nodes in the model are free. To constrain the model, you specify which degrees of freedom are to be constrained for one or more nodes.
Stress analyses are used to identify structure-related problems, typically with the strength, stiffness, and life expectancy of plastic products.
A local coordinate system (LCS) is a set of X, Y and Z axes associated with each node in the model. It is often preferable to use a local coordinate system for assigning constraints and loads to simplify the constraint or load to one direction.
For a Stress analysis, constraints are applied to the model nodes to prevent rigid body motion (global translations and rotations) of the model, in response to the applied loads, whilst not interfering with the shrinkages of the part.
During Stress or Warp analysis, a load, or force, is applied to the part, and the resulting deflections are measured.
