Abstract: | In brittle materials such as concrete and ceramics, fiber reinforcement has beenwidely accepted as an effective way of improving their strength and toughness. In addition, a notable pseudo strain-hardening phenomenon can contribute to a significantly enhanced ductility of the composite when adequately designed fiber system is used. This condition was first proposed by Aveston et al. [1], and later extended by Marshall et al. [2] for continuous aligned fiber reinforced brittle matrix composites. More recently, further extension to randomly oriented discontinuous fiber reinforced composites have been presented [3,4]. Upon satisfying these conditions described in the above mentioned micromechanical models, the ultimate tensile strains of the composites are usually improved by two order of magnitude ( e.g. see [5], [6], [7]). The total fracture energy reaching 35 kJ/m2 was also reported for a 2% polyethylene fiber reinforced cement paste [8]. This kind of ductile fracture resembles metal instead of brittle materials. |
