Shear locking and hourglassing in msc nastran

shear locking. Because of locking, wrong displacements, false stresses, spurious natural frequencies are encountered. Shear locking occurs on use of fully integrated linear elements that are subjected to pure bending. The formulation of these elements “promotes” shear strains that do not really exist Shear locking.

Dr. George F. Sep 14,  · Hourglassing is more pronounced in First order reduced Integration schemes. Use higher order reduced Integration schemes. You might ask why not first order full Integration elements? Strictly no as first order full integrated elements may undergo shear locking. The best way is to add hourglass stiffness to your model.

Linear hexahedral incompatible mode elements (C3D8I) were used to overcome shear locking issues that may arise when modelling flexural waves in fully integrated elements [10, 11]. Four elements were modelled through the thickness of the beam, with the delamination in the centre of the beam modelled by disconnected .

LOCKING IN FINITE ELEMENT ANALYSIS. .Contd  Shear locking occurs on use of fully integrated linear elements that are subjected to pure bending.  Volumetric locking occurs in fully integrated elements when the material behavior is nearly or fully incompressible(poisson’s .
