  2. Direct stiffness method - Wikipedia

    en.wikipedia.org/wiki/Direct_stiffness_method

    One of the largest areas to utilize the direct stiffness method is the field of structural analysis where this method has been incorporated into modeling software. The software allows users to model a structure and, after the user defines the material properties of the elements, the program automatically generates element and global stiffness ...

  3. Structural analysis - Wikipedia

    en.wikipedia.org/wiki/Structural_analysis

    Commercial computer software for structural analysis typically uses matrix finite-element analysis, which can be further classified into two main approaches: the displacement or stiffness method and the force or flexibility method. The stiffness method is the most popular by far thanks to its ease of implementation as well as of formulation for ...

  4. Matrix method - Wikipedia

    en.wikipedia.org/wiki/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 ...

  5. Finite element method in structural mechanics - Wikipedia

    en.wikipedia.org/wiki/Finite_element_method_in...

    The 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 a set of appropriate finite elements interconnected at

  6. Flexibility method - Wikipedia

    en.wikipedia.org/wiki/Flexibility_method

    In structural engineering, the flexibility method, also called the method of consistent deformations, is the traditional method for computing member forces and displacements in structural systems. Its modern version formulated in terms of the members' flexibility matrices also has the name the matrix force method due to its use of member forces ...

    Computers and Structures, Inc. (CSI) is a structural and earthquake engineering software company founded in 1975 [1] and based in Walnut Creek, California, with additional office location in New York. [2] The structural analysis and design software CSI produce include SAP2000, CSiBridge, ETABS, SAFE, PERFORM-3D, and CSiCOL.

  8. Proper orthogonal decomposition - Wikipedia

    en.wikipedia.org/wiki/Proper_orthogonal...

    The proper orthogonal decomposition is a numerical method that enables a reduction in the complexity of computer intensive simulations such as computational fluid dynamics and structural analysis (like crash simulations). Typically in fluid dynamics and turbulences analysis, it is used to replace the Navier–Stokes equations by simpler models ...
