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. 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…

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. Webstrain: [verb] to draw tight : cause to fit firmly. to stretch to maximum extension and tautness. can people eat rocks

WebApr 29, 2024 · 6. A physical structure doesn't care what stress and strain measures you use to model it. It just does what it does. However to make a useful mathematical model, the model has to be simple enough so you can actually work with it. That results in different stress and strain measures for different situations. The thing that needs to stay simple ... WebThe deformation of soft tissues is often described by means of the right and left Cauchy-Green tensors defined as: C =F T F and B = FF T, where F is the deformation gradient.
