ΔΥΝΑΜΙΚΗ ΤΩΝ ΡΗΓΜΑΤΩΜΕΝΩΝ ΔΟΚΩΝ ΣΤΟ ΝΕΡΟ

THE NATURAL FREQUENCIES AND THE CORRECTION COEFFICIENT Z FOR THE THREDIMENSIONAL FLOW WERE COMPUTED. THIS WAS ACCOMPLISHED WITH TIMOSHENKO BEAM THEORY, ANALYTICALLY AND WITH ONE DIMENSION FINITE ELEMENTS, BY INTRODUCING THE CRACK EFFECT WITH LOCAL COMPLIANCE COEFFICIENTS. ALSO WAS ACCOMPLISHED, BY THEORY OF ELASTICITY WITH PLAIN STRESS QUADRILATERAL FINITE ELEMENTS, BY INTRODUCING THE CRACK EFFECT WITH THE CONCEPT OF CRACKED NODE. FOR THE FLUID THE ADDED MASS MATRIX IS COMPUTED BY THE BOUNDARY ELEMENT METHOD OF SOURCES. ALSO WAS COMPUTED, THE LOCAL COMPLIANCE COEFFICIENT IN BENDING, FOR HOLLOW ORTHOGONAL BEAMS.
