Once only accessible at the high-end of manufacturing, modelling and simulation is now widely embraced by the industry as a result of increased processor speeds, the accessibility and usability of software and the reliability and robustness of the models and codes which underpin it.

KAUST

I want to share with you my intention to step down as president of KAUST at the end of my term in November next year. My President’s Circular announcing this to the KAUST community was sent this morning. A global search for my successor will be initiated shortly, and until the next president comes on board, I shall continue to serve.

hi....i m working on ansys(mehanical apdl).....here i m doing non linear material model analysis of a two panel slab....i have chosen material model 1 as multilinear elastic and entered the graph in that and took material no.2 for steel with EX=2E8,PR=.33....units are in SI.....NOW I m getting the warning as"For material 1 at temperature 0 has a tangent slope of its stress strain curve <75000> greater than EX <6.0134717-154>..............can anyone suggest some solution for this....

Dear all,

Layered Shell Displacements

Shell

Layered

Hi,

I am confused regarding displacements calculated through layered shell model in Ansys using Shell 181.

The model is composed of 5 layered sections of different materials (with thicknesses) assigned to an area. The whole laminate is cooled from a reference (zero-strain) (150 C) temperature to a uniform temperature (-40 C).

I need to calculate the difference of displacements between two nodes in the meshed area, for a specific location in layer no. 3. The issue is that I only have nodes in one plane and the results (i think) are interpolated along the thickness. My question is that, is there any method to find displacements at a specific layer in the shell model [as we can find all other results (stress, strains etc.) for different layers]

Wikipedia mistake?

Am I mistaken or is there a mistake in the Wikipedia entry on Mechanical Stress? The index convention used in the text seems to be inconsistent with the illustrations (Figures 1.1, 2.3 and 2.4). In the figures, the second index refers to the direction of traction. But, in the text it is the other way around.
