Analysis of elasto-plastic thin-shell structures using layered plastic modeling and absolute nodal coordinate formulation

Parameter sensitivity of anisotropic elasto-plastic shell

1.Abstract A continuum-based design sensitivity analysis (DSA) applied to the thickness design of the anisotropic elasto-plastic shell structures is developed. Since main interest lies in developing path-following algorithms for solving sensitivity problems of elasto-plasticity, such an incremental or a step-by-step formalism will be employed to implementation into the structural analysis progr...

A Finite Volume Formulation for the Elasto-Plastic Analysis of Rectangular Mindlin-Reissner Plates, a Non-Layered Approach

This paper extends the previous work of authors and presents a non-layered Finite Volume formulation for the elasto-plastic analysis of Mindlin-Reissner plates. The incremental algorithm of the elasto-plastic solution procedure is shown in detail. The performance of the formulation is examined by analyzing of plates with different boundary conditions and loading types. The results are illustrat...

Laminated Composite Shell Element Using Absolute Nodal Coordinate Formulation and Its Application to Ancf Tire Model

Elasto-plastic analysis of reinforced soils using mesh-free method

In this paper the application of the mesh-free method (MFM) for the elasto-plastic analysis of reinforced soils is studied for the first time. The applied mesh-free method is called the radial point interpolation method (RPIM). In MFM, unlike the finite element method (FEM), there is no need of mesh in the traditional sense, and the shape functions are based on nodes. In the present study the r...

Modeling and Simulation of Elasto-Plastic Multibody Systems with Damage

Flexible multibody systems are studied where plasticity is induced by inertial forces. Such a situation may occur when the stiffness of a structure is weakened by an operation under catastrophic environmental conditions. To analyze this phenomenon, plane motions of beam elements with large rigid body motion and moderately large deformation are considered. The equations of motions for the proble...
