ABSTRACT

Energy absorption plays an important role in rock deformation and rock failure. Under compression load, rock fails abruptly which can cause sudden energy release that demonstrates the structural failure. The deformation of rock is based on the energy absorption and dissipation which is found dissimilar for each weathered specimen. Weathered granite namely Grade II, III and IV were tested under static compression load to determine the energy accumulation and dissipation of weathered rock is determined. The results were then compared to rock samples with and without pre-loaded cyclic stress. The comparison is made in order to observe the effect of cyclic stress history on weathered granite samples. Based on the result, it is demonstrated that the weathered granite samples with cyclic stress history absorbed more energy as compared to the samples without preloaded cyclic stress.
