Nonlinear Finite Elements For Continua And Structures

A review of meshless methods for laminated and functionally graded plates and shells

Smoothed particle hydrodynamics method for fluid flows, towards industrial applications: Motivations, current state, and challenges

In the present study the third-order theory of Reddy for composite laminated plates is discretized using a new type of meshless method, a finite point based on the multiquadric radial basis function method. The method allows a very accurate prediction of the field variables.

Analysis of composite plates using higher-order shear deformation theory and a finite point formulation based on the multiquadric radial basis function method

Meshfree method for large deformation analysis–a reproducing kernel particle approach

Aiming to simplify the solution process of elasto-plastic problems, this paper proposes a reproducing kernel particle algorithm based on principles of parametric quadratic programming for elasto-plasticity. The parametric quadratic programming theory is useful and effective for the assessment of certain features of structural elasto-plastic behaviour and can also be exploited for numerical iteration. Examples are presented to illustrate the essential aspects of the behaviour of the model proposed and the flexibility of the coupled parametric quadratic programming formulations with the reproducing kernel particle method.

Elasto‐plasticity revisited: numerical analysis via reproducing kernel particle method and parametric quadratic programming

A description and results from validation studies for the Karagozian & Case (K&C) concrete (KCC) model are presented in this paper. This material model is primarily intended for modeling the dynamic responses of RC structural components. It is based on a partially associative plasticity theory and has proven itself capable of replicating most of the key behaviors of concrete, such as those related to hardening, softening, rate effects, confinement, shear dilatancy, and fracture. Three pressure-sensitive, independent strength surfaces are used by the KCC model to capture the variations in hardening and softening behaviors exhibited by concrete. These three strength surfaces are used to compute a failure surface that reflects the influence on the concrete’s behavior of the current stress and strain states at a material point. This dynamic form of the failure surface is realized by interpolating between pairs of fixed-strength surfaces on the basis of the value of a damage parameter computed by the K...
