Solid mechanics stress and strain
WebBasic equations of elasticity. To determine the distribution of static stresses and displacements in a solid body we must obtain a solution (either analytically or numerically) to the basic equations of the theory of elasticity, satisfying the boundary conditions on forces and/or displacements. The equations thus form a boundary value problem. WebJun 5, 2012 · The term mechanical behavior refers to the response of materials to forces. Under load, materials may either deform or break. The factors that govern a material's resistance to deforming are very different than those governing its resistance to fracture. …

WebStrain. Strain is the response of a system to an applied stress. When a material is loaded with a force, it produces a stress, which then causes a material to deform. Engineering strain is defined as the amount of deformation in the direction of the applied force divided by the initial length of the material. This results in a unitless number ...

WebIf the isotropic solid is subjected only to shear stress τ—i.e., σ 12 = σ 21 = τ, with all other σ ij = 0—then the response is shearing strain of the same type, ε 12 = τ/2G, ε 23 = ε 31 = ε 11 = ε 22 = ε 33 = 0. Notice that because 2ε 12 = γ 12, this is equivalent to γ 12 = τ/G. The constant G introduced is called the shear ...
