An understanding of rock as an engineering material, including analysis of the state of stress in a solid body. Stress and strain tensors, stress and strain invariants, rotation of axis, 3DMohr circles and Hookes Law. Understood the origin and measurement of insitu stress and strain. Analysed rock mass structure, failure mechanisms, and failure criteria. Understood stress around underground openings. Undertaken field density measurement, liquid and plastic limit, compaction, pereameter. UCS, UTS and triaxial testing
