Hi every oneI am doing my master in civil engineering at U.K.M. University in Malaysia. I want to learn 1 FEM software. But I don’t no which of them is better for me ,ansys or abaqus?. My thesis is about concrete filled tubular.
I must model concrete and steel, and I think I face contact problem to define connection between concrete and steel.
I will be very pleased if someone helps me.
The physics associated with self-affine crack formation and propagation is discussed. Some novel concepts are suggested for the mechanics of self-affine cracks. These concepts are employed to model the crack face morphology and, in turn, to solve various problems with self-affine cracks. It is shown that linear elastic fracture mechanics (LEFM) is a special case of self-affine crack mechanics and should be used only in length scales larger than the self-alfine correlation length. The theoretical results are confirmed by available experimental data.
We found that randomly folded thin sheets exhibit unconventional scale invariance, which we termed as an intrinsically anomalous self-similarity, because the self-similarity of the folded configurations and of the set of folded sheets are characterized by different fractal dimensions. Besides, we found that self-avoidance does not affect the scaling properties of folded patterns, because the self-intersections of sheets with finite bending rigidity are restricted by the finite size of crumpling creases, rather than by the condition of self-avoidance.
I work on a project that study impact about Composite and need to analyse it in ANSYS. also I'm eager to learn impact, It's very usefulllll.
thanx.
Dear Fellow Mechanicians:
If you know somebody (including yourself) are looking for faculty jobs, please encourage them to apply to Utah State University. We are filling two tenure-track positions in the broad sense of solid mechanics or thermal science. At least one position for solid mechanics. For details of the job descriptions, please refer to my previous post. You need to apply through the online system at jobs.usu.edu. We will start reviewing the applicants on January 7th, 2008.

This paper presents a geometric discretization of elasticity when
the ambient space is Euclidean. This theory is built on ideas from
algebraic topology, exterior calculus and the recent developments
of discrete exterior calculus. We first review some geometric
ideas in continuum mechanics and show how constitutive equations
of linearized elasticity, similar to those of electromagnetism,
can be written in terms of a material Hodge star operator. In the
discrete theory presented in this paper, instead of referring to
Hi All :
I was wondering why some people prefer to use Non Local Model while some others use Implicit Gradient Model (which can be derived from Non Local Model) .
When implicit Gradient Model is itself derived from Non Local Model ,and its FE implimentation just involves an additional average to be calculated and what is the need to introduce gradient terms ??
Thanks Alot
Kapil
