The bucket foundation breakwater is a new type of structure applied in port and coastal engineering, the stability of which is sustained by the bucket foundation penetrated in soft soil. According to the project of extending breakwaters in Tianjin Port, a three-dimensional finite element model is developed and used in modal analysis based on the Lanczos method. It is resulted that the movement modes...
This paper presents a parallel implementation of the implicitly restarted Lanczos method for the solution of large and sparse eigenproblems that occur in modal analysis of complex structures using the finite element method. The implicitly restarted technique improves convergence of the desired eigenvalues without the penalty of lost of orthogonality keeping the number of factorization steps in a modest...
