  1. (v) Fracture or Breaking Point. It is the point in the stress-strain curve at which the failure of the material takes place.

  2. Aug 4, 2023 · The fracture or breaking point of a material refers to the instant at which a test piece or component reaches its maximum stress/strain resilience and suffers fracture or failure. Different materials have different fracture properties and behaviors.

  3. Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture. This is usually determined for a given specimen by a tensile test, which charts the stress-strain curve.

    Elasticity is the property of solid materials to return to their original shape and size after the forces deforming them have been removed. Recall Hooke's law — first stated formally by Robert Hooke in The True Theory of Elasticity or Springiness(1676)… which can be translated literally into… or translated formally into… Most likely we'd replace th...

    The strength of a material is a measure of its ability to withstand a load without breaking.
    Banerjee, et al. show that when nanoscale single-crystal diamond needles are elastically deformed, they fail at a maximum local tensile strength of ~89 to 98 GPa.

    Imagine a piece of dough. Stretch it. It gets longer and thinner. Squash it. It gets shorter and fatter. Now imagine a piece of granite. Try the same mental experiment. The change in shape must surely occur, but to the unaided eye it's imperceptible. Some materials stretch and squash quite easily. Some do not. The quantity that describes a material...

    A force applied tangentially (or transversely or laterally) to the face of an object is called a shear stress. The deformation that results is called shear strain. Applying a shear stress to one face of a rectangular box slides that face in a direction parallel to the opposite face and changes the adjacent faces from rectangles to parallelograms. T...

    A force applied uniformly over the surface of an object will compress it uniformly. This changes the volume of the object without changing its shape. The stress in this case is simply described as a pressure (P = F/A). The resulting volume strain is measured by the fractional change in volume (θ = ∆V/V0). The coefficient that relates stress to stra...
