10x Faster Midsurface Modeling for Finite Element Analysis of Injection Molded Plastics

By | webinar | No Comments

This presentation discusses best practices for expediting the midsurface geometry process. Specifically, a new semi-automatic or incremental method for creating midsurface geometry will be presented. The concepts mentioned in the presentation will be demonstrated on an injection molded plastic component. The same component required 10 hours to complete with existing pre/post processors, but once the incremental midsurface method is adopted, the process required 1 hour. The MSC Apex incremental midsurface method will be used throughout the live demonstration.

Constructing midsurface geometry and meshes for Finite Element Analysis (FEA) is a process often requiring hours to days to complete. Existing midsurface extraction methods in pre/post processors, while automated, often produce very incomplete midsurface geometry. As a consequence, significantly more time is required before midsurface geometry is completed and meshed.

Reducing the time required to analyze an aircraft avionics door for damage scenarios by 60%

DEMA SpA is a major aerospace supplier that provides work packages for many major aircraft programs such as the Boeing 787, Airbus A380 and A321, ATR 42-72, Augusta Westland AW139, and Bombardier CS100. DEMA recently designed and built an innovative avionics bay pressurized door for a commuter jet. DEMA engineers developed an innovative design concept in which the door is assembled from sheet metal using a machinable plate that saves weight by eliminating the need for mechanical joints. DEMA needed to analyze the ability of the door to meet in-flight structural requirements in spite of multiple damage scenarios that might be incurred during service operations or could result from manufacturing variation in order to determine whether or not the structure maintains a sufficient safety margin. These damage scenario analyses are used as the basis for inspection protocols that are performed on a regular basis to ensure that the door is flight-ready.
