报告摘要：Fiber-reinforced composites offer lightweight, high-strength and high-stiffness solutions for many structural applications. Due to their anisotropic and laminated nature, the fracture and damage mechanisms of such structures are coupled and complex. The prediction of structural performance of composite structures is critical to their design and optimization of material usage. This requires understanding of the interaction of damage mechanisms and their accurate modeling in computational analysis, often at multi-scale levels. Recently, advanced and innovative computational methods have been devised to improve failure prediction based on underlying mechanics and damage observations. This lecture will overview existing computational methods for composites as well as new high-fidelity methods such as the adaptive discrete-smeared crack (A-DiSC) that could point the way to model impact damage and failure of large composite structures. Innovative finite element squared (FE2) methods have potential to solve multi-scale fracture and damage problems in composites by directly incorporating failure mechanisms at the micromechanics levels and enable efficient structural modeling of complex 3D-printed structures. A brief overview of the research activities of the composites materials and structures group at the Dept of Mechanical Engineering, National University of Singapore, will also be presented.
