CompositesWorld, publisher of High-Performance Composites and Composites Technology magazines, as well as the CompositesWorld Weekly newsletter, is presenting a webinar on May 27, sponsored by Altair, titled, "Composites Optimization and Analysis in Space Launch Vehicles: United Launch Alliance (ULA) Utilizes Free Size Optimization for a Doubler Repair of a Gouge Type Defect."

The webinar begins at 2:00 p.m. EDT on May 27 and will last one hour. 

Doublers are commonly used in launch vehicles to repair composite sandwich facesheet defects, such as gouges or depressions, because they locally increase the strength of the facesheet in the area of the repair. Although doublers can be of a different material than the facesheets, they often have comparable strength and stiffness. Therefore, the doubler’s influence on the overall extensional and bending stiffness of the sandwich can be significant. ULA explored the use of OptiStruct, HyperWorks’ structural optimization and analysis solver, to optimize the size and shape of a composite doubler to minimize the stresses.

Participants of the webinar will learn:

  • Concept design synthesis for composites
  • Modeling and analysis of laminated structures
  • Size and shape optimization of composite sandwich structures

The presenters are Tim Harrell, a structural analyst at United Launch Alliance, and Dr. Robert Yancey, vice president—Aerospace Solutions at Altair.
