Article Title: Shear and Interface Properties for Unidirectional, Woven, and Hybrid M21 Particle-Toughened Composites
Article Snippet: .. EST is implemented through the use of a VUMAT in Abaqus which allows for a custom definition of the mechanical constitutive behavior of a material. presents the energy dissipation in a simple manner, in which energy dissipation due to micro-scale cracking is represented by area S and the strain energy density is represented by W . The material has an initial shear modulus of G 120 and a secant shear modulus G 12 s e c which decays until the material reaches a failure criteria strain γ 12 c to enter the crack band. ..

Article Title: Modeling and Progressive Damage Analysis of Hybrid UD/PW Composites under Low-velocity Impact
Article Snippet: This study investigates the low-velocity impact (LVI) damage mechanisms of hybrid carbon fiber-reinforced polymer (CFRP) laminates comprising unidirectional (UD) and plain-woven (PW) plies under different energy levels (17.0, 34.5, and 50.0 J).. The proposed model was developed by coupling finite element analysis with instrumented dropweight experiments to validate intralaminar and interlaminar progressive failure analysis.. The intralaminar model, implemented via a user-defined material subroutine (VUMAT), integrates UD and PW constitutive descriptions and employs a fiber-aligned meshing technique that rotates elements along local fiber directions.
