**Tangent stiffness matrix**— In computational mechanics, a tangent stiffness matrix is a matrix that describes the stiffness of a system in response to small changes in configuration. It represents tangent in that the energy of the system can be thought of as a high… … Wikipedia**Stiffness**— is the resistance of an elastic body to deformation by an applied force. It is an extensive material property.DefinitionThe stiffness, k , of a body is a measure of the resistance offered by an elastic body to deformation (bending, stretching or… … Wikipedia**Matrix stiffness method**— In structural engineering, the matrix stiffness method (or simply stiffness method , also known as Direct stiffness method) is a matrix method that makes use of the members stiffness relations for computing member forces and displacements in… … Wikipedia**Matrix method**— The matrix method is a structural analysis method used as a fundamental principle in many applications in civil engineering. The method is carried out, using either a stiffness matrix or a flexibility matrix. The flexibility method is not… … Wikipedia**Matrix (mathematics)**— Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… … Wikipedia**Direct stiffness method**— As one of the methods of structural analysis, the direct stiffness method (DSM), also known as the displacement method or matrix stiffness method, is particularly suited for computer automated analysis of complex structures including the… … Wikipedia**Mass matrix**— In computational mechanics, a mass matrix is a generalization of the concept of mass to generalized coordinates. For example, consider a two body particle system in one dimension. The position of such a system has two degrees of freedom, the… … Wikipedia**Metal matrix composite**— A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. The other material may be a different metal or another material, such as a ceramic or organic compound. When at least three materials are … Wikipedia**Orthotropic material**— Wood is an example of an orthotropic material. Material properties in three perpendicular directions (axial, radial, and circumferential) are different. An orthotropic material has two or three mutually orthogonal twofold axes of rotational… … Wikipedia**Hooke's law**— models the properties of springs for small changes in length Prof. Walter Lewin explains Hooke s law, in … Wikipedia**Finite element method in structural mechanics**— Finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by… … Wikipedia
