The mixed finite element for quasi-static and dynamic analysis of viscoelastic circular beams
Fethi Kadioglu and A. Yalcin Akoz

 
Abstract
    The quasi-static and dynamic responses of a linear viscoelastic circular beam on Winkler foundation are studied numerically by using the mixed finite element method in transformed Laplace-Carson space. This element VCR12 has 12 independent variables. The solution is obtained in transformed space and Schapery, Dubner, Durbin and Maximum Degree of Precision (MDOP) transform techniques are employed for numerical inversion. The performance of the method is presented by several quasi-static and dynamic example problems.
 
Key Words
