Stress and Strain

Stress and Strain. Stress. Force/Area Pressure is one form of Stress Units: Pascals (1 bar = 1 atm = 100,000 Pa) Normal Stress: Perpendicular to surface Compression vs. Tension Shear: Parallel to Surface. Stress. Hydrostatic Stress (usually compressional) Uniform in all directions.
