What is plane stress, plain strain, asymmetry?

What is plane stress, plane strain, asymmetry? Obviously, gaining insight before start modeling can be highly profitable in order to boast the precision and reduce the computational expenses. In this article, three main simplification concepts have been introduced. Plane stress assumption: an element is called to be under plane stress condition if the stress vector is zero across a […]

Why ABAQUS is perfect for Civil Engineering

Why ABAQUS is perfect for Civil Engineering Obviously, Finite Element Method (FEM) is one of the most effective methods for numerical modeling. Among several pieces of civil engineering software, which are designed based on FEM,  Plaxis, SAP and Abaqus are probably the most well-known ones. In this article we give you a summary of some […]

Convergence Issues with ABAQUS

Convergence issues are probably the most unpleasant experience of the users. Almost all ABAQUS users have experienced them. To solve such error, first you need to know what has caused it, and then you can take proper strategies. To be honest, convergence is usually one of the most challenging topics in an numerical modeling. Based […]

Soil Direct Shear Test

General Procedure Direct shear test has been designed to estimate the shear strength properties of soil or rock material. Also it can carried out to gain insight about discontinuities in soil or rock masses. The test is usually carried out on four soil specimens. To reach accurate results, It is important to use relatively undisturbed soil sample. As it is shown […]

Pressuremeter test (PMT)

What is PMT? The pressuremeter test (PMT) is an in-situ test to estimate the amount of some soil parameters such as the elastic modulus. In simple words, PMT is performed by applying pressure to the sidewalls of a borehole, measuring the corresponding soil deformation. Briefly, a probe is placed in the borehole, then it is […]
