Wasatch Composite Analysis has the detailed knowledge to properly build and align material coordinate systems in a finite element model such that the correct “hour glassing” displacement behavior is observed for composite structures under cryogenic loading.
Wasatch Composite Analysis has the in depth knowledge to evaluated the proper structural response of composite and metallic components under the cryogenic temperature loading of space environments as low as 25 Kelvin (-415⁰F). WCA understands the importance of defining the correct Coefficient of Thermal Expansion (CTE) material behavior. As show in the chart below, CTE of stainless steel can change significantly as materials cool to cryogenic environments. Without the knowledge of the correct material behavior, the proper component response and strength margins cannot be calculated.
