New Model Accurately Predicts Deflection and Stress in HSP Structures with Minimal Computational Complexity
Feb 18, 2021
Comtek’s Engineering Manager, Stefan Kloppenborg, along with former R&D employee, Hart Honickman, recently published a new mathematical model that describes the way composite materials respond to bending moments and shear forces. This model predicts the deflection and stress distribution within a beam made from a layered composite material. This new model provides more accurate results compared with a Timoshenko First-Order Shear Deformation Theory (FSDT) and is much less computationally complex than Finite Element Analysis (FEA).
This model is particularly well suited to analyzing sandwich panels, a key material used in Comtek’s lightweight composite product offering. Analytical tools like this new model allow Comtek to perform rapid trade studies while developing new products.
Full details of the model are provided in a journal article in Mathematics and Mechanics of Solids:
