pureutumispiste

Puretumispiste refers to the point at which a material begins to deform plastically under stress. Before reaching the puretumispiste, a material will behave elastically, meaning it will return to its original shape once the stress is removed. Beyond this point, however, the material undergoes permanent deformation and will not recover its initial form. This concept is crucial in materials science and engineering, as it defines the limit of a material's usefulness in applications where elastic behavior is required.

The puretumispiste is often associated with the yield strength of a material. While the terms are sometimes used interchangeably, yield strength is a more precise measure determined through standardized testing, typically a tensile test. The exact location of the puretumispiste can be influenced by various factors, including the material's composition, its processing history, temperature, and the rate at which stress is applied. Understanding this point is vital for designing structures and components that can withstand anticipated loads without permanent damage. Exceeding the puretumispiste can lead to structural failure or reduced performance.
