A Semi-Discrete Model for Progressive Damage and Failure of Fiber Reinforced Laminates
15 Nov 2021 | Contributor(s):: Anthony M Waas
High-strength and high-stiffness carbon fiber-reinforced polymer composite laminates (CFRP) are being increasingly used for primary load bearing structures in many industries. The most common material system used is based on thermoset resins (matrix material), which come in the form of convenient...
