Material stress is the force per unit area within materials that arises from externally applied forces, residual forces, or changes in temperature, which can cause deformation or failure. Understanding material stress is crucial for ensuring the safety and functionality of structures, as it helps in designing materials and systems capable of withstanding anticipated loads and conditions.

Material stress

Force per unit area is known as pressure, a fundamental concept in physics that quantifies the distribution of force over a surface. It is crucial in understanding how forces are applied in fluids, solids, and gases, influencing phenomena such as buoyancy, atmospheric pressure, and material stress responses.

Deformation refers to the change in shape or size of an object due to applied forces or changes in temperature. It encompasses both elastic deformation, which is reversible, and plastic deformation, which is permanent, and is a critical concept in fields such as materials science, geology, and mechanical engineering.
