There are numerous varieties of stresses and strains, together with tensile stress (pulling pressure), compressive stress (pushing pressure), shear stress (pressure utilized parallel to a floor), tensile pressure (elongation), compressive pressure (shortening), and shear pressure (deformation in form).
The connection between stress and pressure is usually represented by a stress-strain curve. This curve offers insights into the fabric’s habits beneath growing stress ranges. It helps decide the fabric’s elastic restrict, yield level, and supreme tensile power.
Linear Elastic Habits
When a cloth displays a linear relationship between stress and pressure, it’s mentioned to be behaving elastically. Because of this the fabric returns to its unique form upon elimination of the utilized stress. The slope of the linear portion of the stress-strain curve represents the fabric’s Younger’s modulus, which is a measure of its stiffness.
Plastic Deformation
Past the yield level, the fabric undergoes plastic deformation, the place it doesn’t return to its unique form after the stress is eliminated. This everlasting deformation is attributable to the irreversible motion of atoms throughout the materials.
Failure
If the stress utilized to a cloth exceeds its final tensile power, it can fail. This failure can happen by way of rupture (breaking up), fatigue (repeated loading), or creep (gradual deformation beneath sustained stress).

|---|---|
| Tensile | Tensile |
| Compressive | Compressive |
| Shear | Shear |
