A representation of deformation tensors in curvilinear coordinates is useful for many problems in continuum mechanics such as nonlinear shell theories and large plastic deformations. Let denote the function by which a position vector in space is constructed from coordinates . The coordinates are said to be "convected" if they correspond to a one-to-one mapping to and from Lagrangian particles in a continuum body. If the coordinate grid is "painted" on the body in its initial configur… WebBritannica Dictionary definition of STRAIN. 1. [+ object] : to injure (a body part or muscle) by too much tension, use, or effort. I strained my back trying to lift the couch. Too much computer work strains the eyes. He strained a muscle in his leg. — compare sprain. 2. : to try very hard to do or get something.

WebJan 17, 2024 · Strain: Check Meaning, Formula and Types. Strain: When a specific force is applied to an object, people wonder about how the object will move subsequently. However, we fail to examine how the force can impact the object’s structure. Bridges are a wonderful illustration. When automobiles move across a bridge, their weight creates a downward pull.

Green strain is usually defined implicitly by the … WebIn engineering, strain is not a measure of force, but is a measure of the deformation produced by the influence of stress. For tensile and compressive loads: (2.5) Strain is dimensionless, so it is not measured in metres, kilogrammes, etc. The commonly used unit is microstrain (μstrain), which is a strain of one part per million.
