In Situ Stresses Stress Measurement

Stress is a concept which is fundamental to rock mechanics principles and applications There are three basic reasons to understand stress in the context of engineering rock mechanics There is a pre-existing stress state in the ground and we need to understand it both directly and as the stress state applies to analysis and design...

What is a Compressive Stress

Dec 17 2016 0183 32 Compressive stress is a force that causes a material to deform to occupy a smaller volume When a material is experiencing a compressive stress it is said to be under compression A high amount of compressive stress such as tensile stress leads to failure due to tension A compressive stress causes a material to compress or shorten...
