Unstable Fracture Behavior of Rubber Toughened Poly(Styrene-co-Acrylonitrile)

摘要: A linear elastic fracture mechanics (LEFM) approach was used to study characteristics of ABS materials. The effects crack (ligament) length and rubber content on the microscopic deformations taking place at front tip in bulk specimens were investigated. results fractography studies showed that, addition content, are influenced by length. For some materials this manifests itself as a change macroscopic response. ligament dependent behavior increased for samples with higher contents. also although unstable growth is dominant micromechanism deformation, stable propagation still occurred compositions. All parameters, including toughness, energy, plastic zone size, opening, content. changes and, consequence, macrosc...
