20.500.12556/RUL-32206 Quadrilateral Finite Element with Embedded Strong Discontinuity for Failure Analysis of Solids We present a quadrilateral finite element with discontinuous displacement fields that can be used to model material failure in 2d brittle and ductile solids. The element provides mesh-objective results. The element's kinematics can represent linear displacement jumps along the discontinuity line in both normal and tangential directions to the line. The cohesive law in the discontinuity line is based on rigid-plasticity model with softening. The material of the bulk of the element is described by hardening plasticity model. Static condensation of the jump-in-displacements kinematic parameters is made, which provides standard form of the element stiffness matrix. However, in order to make the discontinuity growth algorithm more robust, the continuity of the failure line between the elements is enforced. Several numerical tests show that the element can describe constant and linear separation modes without spurious transfer of the stresses. Other numerical examples represent failure of pure concrete, composite and metal 2d solids. civil engineering embedded discontinuity material failure softening gradbene konstrukcije vgrajena neveznost porušitev materiala mehčanje true false false Techno Press Angleški jezik Angleški jezik Neznano 2015-07-10 10:13:07 2015-07-10 10:13:07 2022-11-21 15:53:43 0000-00-00 00:00:00 2010 0 0 Str. 223-260 št. 3 Letn. 69 2010 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.07 1526-1492 10.3970/cmes.2010.069.223 5301345 1931361 Quadrilateral_CMES_Brank_k.pdf Quadrilateral_CMES_Brank_k.pdf 1 B2DF4A5BEA2BFA669283DF036CB05988 d1f0fda58c8733a01f3c807a272e15c5566f34e9b567edebb0c3a2f74162aff4 1588ef2a-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/ce6ee7a5-4839-401a-a347-ab7f2dc846af https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=85719 Fakulteta za gradbeništvo in geodezijo 0 0 0
