New Developments in Analytical Modeling of Mechanical Behavior of ECC

摘要: Finite element method in conjunction with an appropriate material model may serve as a suitable tool to analyze the structural performance of Engineered Cementitious Composites (ECCs) - short fiber reinforced composites, which exhibit pseudo strain-hardening behavior and multiple cracking under tension. Several such models are reviewed some new formulations proposed. The represents composite state equivalent continuum identical macromechanical properties. constitutive law is obtained relationship between overall stress strain representative volume (RVE). RVE modeled solid intersected by fiber-bridged matrix cracks. In order relate relative displacements crack faces bridging tractions, generalized derived. A density also discussed. resulting for implementation FEM, yet maintains transparent link microstructure.
