Finite elements method is quite easy in comparison with analytical methods, , however if the user misuse it the outcome will be inaccurate or even wrong. As a result, any numerical model must be verified by experiments or field measurements. Only then the model is acceptable for use. Since there is no specific guidelines for […]
In finite element (FE) methods, the calculating of element stiffness is of a fundamental importance to compute the deformation of the element. Depending on the complicity and importance of the problem the stiffness matrix can be calculated by different accuracy. One of the well-known method for numerical integration of two-dimensional integration is Simpson’s rule, which […]
