Mixed Method of Limit Analysis: Validation and New Results for Porous Coulomb Materials
نویسندگان
چکیده
The first purpose of this work was to develop efficient upper bound limit analysis tools for axisymmetric limit analysis (LA) problems, together with avoiding the specific singularities of this case of symmetry. The second main purpose concerns assessments and predictions about the macroscopic criterion of a porous material on the basis of the hollow sphere or spheroid model with a frictional matrix, without any smoothing hypothesis of the plasticity criterion.

A novel discrete singular convolution (DSC) formulation is presented for the seepage analysis in irregular geometric porous media. The DSC is a new promising numerical approach which has been recently applied to solve several engineering problems. For a medium with regular geometry, realizing of the DSC for the seepage analysis is straight forward. But DSC implementation for a medium with ir...
متن کاملA New Approach for Determination of Neck-Pore Size Distribution of Porous Membranes via Bubble Point Data
Reliable estimation of the porous membranes neck-pore size distribution (NPSD) is the key element in the design and operation of all membrane separation processes. In this paper, a new approach is presented for reliable of NPSD of porous membranes using wet flow-state bubble point test data. For this purpose, a robust method based on the linear regularization theory is developed to extract NPSD...
متن کاملInterior Modification of Nano-Porous Fillers to Fabricate High Performance Mixed Matrix Membranes
A new method is developed to enhance the gas separation properties of mixed matrix membranes (MMMs) by interior modification of an inorganic nano-porous particle. Ship-in-a-bottle (SIB), as a novel synthesis strategy, is considered to encapsulate a polyaza macrocyclic Ag-ligand complex into the zeolite Y, which is resulted in a new host-guest nano-composite. It is consequently incorporated into...
متن کاملA refined inverse hyperbolic shear deformation theory for bending analysis of functionally graded porous plates
The modern engineering structures require the advanced engineering materials to resist the high temperatures and to provide high stiffness. In particular the functionally graded porous materials (FGPMs) introduced are expected to have these desired properties, consequently eliminating local stress concentration and de-lamination. In the present paper, a new shear strains shape function is chose...
متن کاملNumerical Evaluation of Hydraulic Fracturing Pressure in a Two-Phase Porous Medium
Hydraulic fracturing is a phenomenon in which cracks propagate through the porous medium due to high pore fluid pressure. Hydraulic fracturing appears in different engineering disciplines either as a destructive phenomenon or as a useful technique. Modeling of this phenomenon in isothermal condition requires analysis of soil deformation, crack and pore fluid pressure interactions. In this paper...
