Yes, all bad. I looked at many sources and none of them follow a straightforward problem without shortcuts that obscure the method or missing key details or not explaining where things go or mixing numbers and matrices or whatever.Arjan82 said:
The Global Stiffness Matrix is a mathematical representation of the stiffness of a structure or system. It is used in engineering and physics to analyze the behavior and stability of a structure under different loads and conditions.
The Global Stiffness Matrix is calculated by combining the individual stiffness matrices of each element in the structure. The individual stiffness matrices take into account the material properties, geometry, and boundary conditions of each element.
The size of the Global Stiffness Matrix is important because it determines the number of equations that need to be solved to analyze the behavior of a structure. The larger the matrix, the more complex the structure and the more computations are required.
The size of the Global Stiffness Matrix is affected by the number of elements in the structure, the number of degrees of freedom, and the type of analysis being performed. For example, a 3D structure will have a larger matrix than a 2D structure.
Yes, the size of the Global Stiffness Matrix can be reduced by using techniques such as symmetry and substructuring. These methods help to simplify the structure and reduce the number of equations that need to be solved, making the analysis more efficient.
