Basic Sciences - Stress - Strain Curve
Description
This video lecture provides an introduction to the stress strain curve, a fundamental concept in materials science. It outlines the relationship between stress (measured in Newton meters squared) and strain (dimensionless). Key regions of the curve are discussed: the elastic region, where materials return to their original shape after stress is removed, and the plastic region, where permanent deformation occurs. Definitions of critical points in the curve are provided, including the yield point, which marks the transition between elastic and plastic deformation, and the ultimate tensile strength, the maximum load a material can sustain before failure. The concepts of Hooke's Law and modulus of elasticity are also highlighted, emphasizing that a higher modulus indicates a stiffer material. The lecture effectively illustrates these concepts with a focus on understanding their implications in practical applications.
