Locking and shear scaling factors in C° bending elements

摘要: Abstract Two types of locking are identified in linear field C° elements: caused by shear resistance constant curvature deformation and deformation, respectively. Locking the first type can be ameliorated decoupling bending from shear, which some elements achieved selective reduced integration. Once modes decoupled, a scaling factor on stiffness used to alleviate second locking. These findings explained terms displacement, rotation beam element applied improvement triangular plate element. It is shown that resulting free performs excellently wide variety problems.
