The Displacement Discontinuity Method
{"Image DocumentName": "The Displacement Discontinuity Method", "Image ImageDescription": "(1) bi. s. n. (N) bj. (i) (j) computer code. BEMCOM. influence coefficients of Ds(j) and Dn(j) on stresses or displacements over. the i-th element. known tangential and normal stresses or displacements acting on the i-th element. The discretisation of Displacement Discontinuities is made by subdividing the crack into a number N of DD elements. In the hypothesis of elastic behaviour of the material, knowing the analytical solution for a single DD element, it is possible to calculate at any point of the body, stresses and displacements due to the crack, by adding up the effects of the N elements. the solving system, made up of 2N equation is given here, where. (click mouse) The method has been implemented in the computer code BEMCOM, which allows the simulation of open and closed cracks, both in tensile and compressive stress fields. unknown displacement discontinuities in the tangential and normal directions, in the centre of the j-th element.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
