  • Stress, Strain, and the Stress-Strain Curve | Materials

    The strength increase due to work hardening must compete with the strength decrease due to necking. The maximum value of stress on an engineering stress-strain curve is called the "ultimate tensile strength." That is the highest load the sample could possibly bear.

  • What is Tensile Strength? - Matmatch

    Tensile strength refers to the amount of load or stress that a material can handle until it stretches and breaks. As its name implies, tensile strength is the material's resistance to tension caused by mechanical loads applied to it. Terms such as ultimate tensile strength (UTS) or ultimate strength are used interchangeably with tensile strength.. A particular material's response to

  • Strength of Materials - Basics and Equations

    Ductile materials have a fracture strength lower than the ultimate tensile strength (UTS), whereas in brittle materials the fracture strength is equivalent to the UTS. If a ductile material reaches its ultimate tensile strength in a load-controlled situation, it will continue to deform, with no additional load application, until it ruptures.
