Abstract
• Our project describes a modified finite strip method embracing the harmonic coupled Fourier series treatment. The uncoupled formulation represents a semi-analytical finite element process. The linear analysis takes advantage of the orthogonally properties of harmonic functions in the formulation. In the case of the geometric stiffness matrix computation, the integral expressions contain the products of trigonometric functions with higher order exponents and here the orthogonally characteristics are no longer valid. All harmonics are coupled, and the stiffness matrix order and bandwidth are proportional to the number of harmonics used. • In this project the stability and dynamic characteristics of homogeneous or composite thin-walled elements of arbitrary open and closed cross-section will be studied. The influence of axial force, end moments, shear deformation and warping effect on stability and dynamic characteristics of beams shall be analysed. • The investigation of the stress-strain field in rock mass around cavities having spherical, infinite cylindrical and oblong ellipsoidal shapes will be included. • We will design a promising original model of a system of wave energy conversion into electricity aimed to utilize power of ocean waves on the basis of fundamental physical principles. • We will combine various parallelization techniques and architectures with suitable programming models (MPI, CUDA, OpenMP, cloud and grid computing) to speed up necessary computations.
