Geometry of Non-Linear Continuum Mechanics

Submitted by Giovanni Romano on

This is an attempt to contribute to bring the discussion on non-linear issues in Continuum Mechanics (CM) under the comprehensive supervision of modern differential geometry (DG). Some people would say that engineers do not need so much mathematics, but such an opinion is a sure indicator of lack of knowledge of the matter. In fact I am an engineer, a University teacher and a designer in Structural Engineering and my experience is that a lot of troubles would have been saved to me by a basic training in DG.

How to get inside the ABAQUS incremental/nonlinear static solver

Hi guys,



I'm working on an ABAQUS extension/plug-in of a sort and I'd like to replicate results for a single 4-node plane stress element produced by the ABAQUS incremental/nonlinear static solver.



I assumed the relationship is:

t[K] {Δx} = t+Δt {P} - t{F}



This is how I went to obtain these values:

[K] - element stiffness - by using *ELEMENT MATRIX OUTPUT

Journal Club Theme of December 2011: Mechanics of Porous Materials

Submitted by john.balk on

Porous materials can be created by a variety of methods and exhibit properties that are advantageous in certain applications, e.g. insulation, energy absorption, and core materials in sandwich panels. As the length scale of the pores/ligaments is reduced below one micron, size effects arise and cause changes in the deformation mechanisms that operate in the ligament material. The mechanical properties can change dramatically, especially for so-called “nanoporous metals”, which have pores and ligaments as small as a few nanometers.
