|
| This paper developed a stress-based finite element method for solving a sliding beam problem. Conventionally, the
displacement-based finite element method is usually in computational solid mechanics, but the method cannot satisfy the compatibility
of inter-element stress fields and the stress boundary conditions. These problems yield the inaccuracy of approximated solutions.
However, the stress-based finite element method can solve these problems. Besides, the numerical examples demonstrate that the
accuracy of this method is higher than that of the displacement-based method based on the same number of degrees of freedom. The
sliding beam problems have diverse engineering applications. The most challenging task for this problem is necessarily to construct
a varying-length beam element. This paper presents a varying-length beam element for the stress-based finite element method. The
dynamic simulations reveal that the results are in good agreement with those in literature. |
