It is difficult to reminisce over my own formative years without sensing

the sharp contrast with the far more difficult situation faced by the

young generation today. My generation, and especially my own narrow age

range within that generation, had things easier, I think, than any group

before or after. I entered Lehigh for undergraduate studies one year

after Sputnik. It was a time when support for science and engineering

was enlarging fast, when opportunities were abundant. There were plenty

maximum entropy

In the attached paper, we construct new generalized coordinates for arbitrary polytopes in d-dimensions (polygons and polyhedra in 2- and 3-dimensions, respectively) using the principle of maximum entropy. The paper is to appear in Computer Graphics Forum and will be presented at the SGP'08 Conference in Denmark.

Hi pals,

Load-displacement curve for concrete

crack propagation

smear cracking model

I am trying to predict load-displacement curve for concrete cube numerically through ABAQUS. I am just beginer with ABAQUS, I have gone through the concrete material models available in ABAQUS. I found that smeared crack model well suite for analysis. Initially I am simulating a 2D model, I am using plane stress elements with static, Riks options, even I could able to complete the analysis, I am confused how to view the cracked elements and how to plot load-displacement curve.
