When I analyze a quiet complex spatial structure, error information warn that: the direction of the beam element is
not correct.

From abaqus document 26.3.4 I know we can
nominate the direction of beam element by adding additional node.It is clear
that this node should be off the axis of the element,any additional constrians?

May I define a random node in the space
which is far far away from my structure, then I add this node as unique
additional node?

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]

greetings :)

i've got this beam, 1x0.24x0.15 (x,y,z) respectively .!

i wanna mesh it, to obtain the following:
first element's length in x-direction is: 0.02
last element's length in y-direction is: 0.045
rest elements (17 middle elements) are: 0.055

y and z direction is according to the global manual size

can anyone help :), thanks alot

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.  

We have an equipment and technology for determination of residual stresses. They are based on the hole-drilling method and electron speckle
interferometry (ESPI-HD method).
