Finite Element Analysis

• Finite element analysis using ABAQUS and ANSYS to predict strength, stiffnesses, displacement, buckling stability, and complex stress/strain behavior of structural details.
• Nonlinear solutions including progressive failure, large displacement analysis, section collapse, material strain-softening and plasticity behavior.
• In-plane progressive failure analysis using stress-based and/or fracture mechanics failure criteria, built-in damage initiation and evolution capability in ABAQUS, custom user-defined materials and elements, and Autodesk Simulation Composite Analysis (previously Firehole Helius:MCT).
• Interlaminar failure analysis of delaminations, disbonds, and/or flaws including matrix damage initiation, and delamination onset and growth under both static and fatigue loading.
• Extensive experience with cohesive and VCCT interface elements including custom, user-defined interface elements.
• Analysis of structural joints including bolted and bonded configurations.
• Rapid 3D solid meshing of wind turbine blades using NSE’s “bladeMesher” in-house software.
