Abstract: The development of basalt fiber reinforced composite is an important milestone in improving the mechanical performance and durability of concrete construction. Basalt fiber is environmentally safe, non toxic, non corrosive and it possess high resistance against low and high temperatures. Incorporation of basalt fiber as reinforcement in concrete is one of the recent developments and the detailed information regarding its characterization is scanty in literature. The present study aims towards mechanical characterization of basalt fiber reinforced composite under compressive loading. Experimental investigation has been carried out on basalt fiber reinforced composite cylinder and cubes having different amount of basalt fibers. The volume fractions of basalt fibers used for studies ranges from 0.3% to 2%. Based on experimental investigation, effect of different volume fraction of basalt fiber has been studied under compression and optimal volume fraction of basalt fiber has been arrived

Abstract: In this paper, seven fatigue crack growth models, namely Priddle, McEvily, Weertman, Collipriest, Broek, Walker and Forman have been examined. The mean stress effect on fatigue crack growth rate is commonly introduced into fatigue crack growth (FCG) relation through the stress ratio, R. Therefore, the ability to correlate and predict the fatigue crack growth rate, FCGr, for different R values is of significant importance for damage tolerant design. Performance of the crack driving force of these models in accounting stress ratio effects in fatigue crack growth rate is evaluated by fitting a lowess curve on transformed FCG data. Experimental fatigue crack growth data of a typical Al 2024 T351 obtained under constant amplitude loading tests for six load ratios has been used in the present work. From the studies carried out, it is observed that Walker and Collipriest models are found to be in good agreement with the experimental FCG data
