stress

• Stress (mechanics), the average amount of force exerted per unit area. It is the internal resistance a material offers to being deformed and is measured in terms of the applied load. The effects of mechanical stress on a polymer? can be measured using dynamic mechanical analysis.
• Compressive stress, the stress applied to materials resulting in their compaction. It is the ability of a material to resist being crushed.
• Tensile stress (also referred to as tension) is the stress state leading to expansion.
• Yield stress, the stress at which a material begins to deform plastically.
