Implementação do cálculo do Fator de Cholesky diretamente a partir da matriz de rigidez do elemento estrutural
In a static analysis the unknowns may be found by rneans of obtaining a factor of the stiffness matrix of the structure. The most popular solution method involves the transformation of this matrix into an upper triangular matrix, the Cholesky factor. Here, it is shown how this factor may be …
