it is a NAVAL POSTGRADUATE university MONTEREY CA document procured by means of the Pentagon and made on hand for public unencumber. it's been reproduced within the top shape to be had to the Pentagon. it's not spiral-bound, yet relatively assembled with Velobinding in a delicate, white linen disguise. The Storming Media record quantity is A708073. The summary supplied through the Pentagon follows: A shell formula was once constructed from a three-d stable. Tile shell aspect has 4 comer nodes at which there are 3 displacements and 3 rotations as nodal levels of freedom, and contains either transverse shear and transverse basic deformations. Tile aspect makes use of diminished integration alongside the in-plane axes and fill integration alongside the transverse axis. Tile formula comprises the Gurson constitutive version for void development and plastic deformation. An set of rules for good options of the nonlinear constitutive equations can also be constructed. Hourglass mode regulate is supplied by way of including a small fraction of inner strength decided via fill integration alongside the in-plane axes and diminished integration alongside the transverse axis. Implementation into either a really good examine finite point application and DYSMAS, a by-product of DYNA3D, is mentioned. Numerical examples are supplied to make sure the accuracy of the recent point and to teach the significance of the transverse general pressure, void results on plastic pressure, and the need of utilising a drilling second.
