A 4‐node quadrilateral membrane element with in‐plane vertex rotations and modified reduced quadrature
Nielen Stander, Edward L. WilsonAn assessment is made of a 4‐node quadrilateral membrane element with one rotational and two translational degrees of freedom per node, as formulated by Taylor and Simo. The…
Occurrence of spurious mechanisms in computations of strain‐softening solids
René de Borst, Jan G. RotsThe behaviour of cracked finite elements is investigated. It is shown that spurious kinematic modes may emerge when softening type constitutive laws are employed. These modes are…
A concrete material model based on non‐associated plasticity and fracture
Eduardo N. Dvorkin, Alberto M. Cuitiño, Gustavo GioiaA concrete material model is presented. The model is based on non‐associated plasticity for the pre‐failure and ductile post‐failure regimes and fracture (smeared crack approach…
Finite element solution of turbulent pipe flows
Mo‐Hwa Wang, Klaus‐Jürgen BatheThe primitive variable finite element formulation is used in a straightforward manner to solve for two turbulent pipe flows. The solution is based on the use of the Nikuradse—van…
A new partitioning strategy for efficient re‐analysis of large structural systems
Ahmed K. Noor, Jeanne M. PetersA computational procedure is presented for the re‐analysis of large unsymmetric structural systems. The procedure is based on a novel partitioning strategy in which the responses…
A mixed finite element for laminated composite plates based on the use of bubble functions
Peter M. Pinsky, Raja V. JastiA new laminated composite plate finite element is proposed that is numerically stable and accurate in displacements and stresses, including transverse shear stress. The…
Numerical solutions of one‐dimensional rheological models of combined consolidation and creep
H.R. Thomas, K. BendaniA solution algorithm which enables various rheological models of combined one‐dimensional consolidation and creep to be accommodated in a unified approach, is used to solve three…
Accurate pore pressure calculation in undrained analysis
D.V. Griffiths, C.O. LiA simple procedure for accurate calculation of pore pressures in undrained elasto‐plastic materials is described. An 8‐node element is used, with ‘reduced’ integration during…
