OptiStruct - Equivalent Plastic Strain Response for Optimization

Equivalent plastic strain can be used as an internal response when a nonlinear response optimization is run using the equivalent static load method. This is made possible through the use of an approximated correlation between linear strain and plastic strain, which are calculated in the inner and outer loops respectively, of the ESL method.

Tips & Tricks

OptiStruct - Contact Pressure, Force as a Response for Optimization

Contact Pressure can be used as an internal response when a model with contact and optimization is run. Contact pressure response is activated using RTYPE=CNTP option. The PTYPE should be set to CONTACT and the corresponding CONTACT Bulk Data ID(s) can be referenced on the ATTi field.

OptiStruct - Failure Response for Topology Optimization

Factor of Safety (FOS) and margin of safety (MOS) optimization responses are now available for Topology optimization. It is calculated using NORM approach on design domain. All optimization types are now supported including Topology.

Tips & Tricks

OptiStruct - Neuber Optimization Response in Nonlinear Subcase

Neuber Stress and Neuber Strain sensitivities are supported for optimization in small displacement NLSTAT. It was already supported for optimization in FASTCONT analysis. It is supported only for small displacement analysis, it is not supported for large displacement. Once Neuber response is defined, the material will be treated as linear and MATS1 props are used only for Neuber correction. It is supported for solids as well as shells. It is supported for all optimization types except topology & freesize optimization.

Tips & Tricks

OptiStruct - Manufacturing Constraints for Composite Optimization

Certain manufacturing constraints are important when designing composite laminates, like balancing of plies, thickness of plies, etc. ln OptiStruct, manufacturing constraints can be defined during free size optimization, shuffling optimization for a better manufacturability and desired stacking sequence. The following are some of the manufacturing constraints which can be used depending on the requirement.
