Theoretical material properties
The stress-displacement, or vs x, relationship during fracture can be approximated by a sine curve, , up to /4. The initial slope of the vs x curve can be related to Young's modulus through the following relationship: where • is the stress applied. The theory began with the consideration of the behavior of one and two dimensional members of structures, whose states of stress can be approximated as two dimensional, and was then generalized to three dimensions to develop a more complete theory of the elastic and plastic behavior of materials. Visa mer The field of strength of materials (also called mechanics of materials) typically refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods … Visa mer In the mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. The field of strength of materials deals with forces and deformations that result from their acting on a material. A load … Visa mer • Fa-Hwa Cheng, Initials. (1997). Strength of material.
