For the mesh,
ELEMENT SHAPE: Quad
For the material, I considered those for silicone rubber
Mechanical: hyperelasticity
Strain energy potential: Neo-Hooke
Input source: coefficients
C10: 1
D1: 0.0001
Tbh, I took the data from a video.
Load:
I use '20' meaning 20 N.
Is it okay for silicone...
I am doing the simulation of simple shear of a square using quadrilateral element type for the mesh. The material properties being Neo-Hookean.
The abaqus error message and warnings are like follows:
'RELAX STIFFNESS IS NOT A VALID CHOICE FOR THE HOURGLASS PARAMETER ON THE *SECTION CONTROLS...
I am currently working on a simple continuum model to demonstrate my students the pure shear analysis on an FEA solver.
Only ABAQUS is available to me. So I am using it for the demonstration.
I am using non-linear strains for the analysis and applying shear loads on a 2D square so that it...
We were talking about lateral swway only arising from let's say a seismic load, and beams and columns axially rigid.
So what you would get, write your stifness marrtix row by row and let's see!
I am sure even though it is a 2-storey, the stiffness matrix can not be :
2k and - k in the first row and
- k and k in the second row?
Plus there is a pin support at one end
What will be the elements in the stiffness matrix?
Can somebody help here please? Thank you
No worries, it makes sense for the beam to be assumed to be axially rigid.
But then what would be the single expression for its stiffness, I personally think it should be a 2 x 2 stiffness matrix
I saw a frame on the web, kinda corresponding to what you are saying, in terms of a single degree.
So you mean the frame below can have a single value for representing its stiffness, so what expression would you get for a single value from that system?
If you say so, then for that 2-storey...
Ahaa, that makes sense, so only the element of the matrix concerned with that displacement will be considered and the rest of the elements disregarded?
Hox can a frame have a single element to represent its overall stiffness?
I found that in a book. From what I remember, a single-storey or double or multi-storey have a matrix of stiffness.
Only a structural member can have one element to represent its stiffnees?
When I ran a job "job W+G-action-20x", I got this error:
Error in job W+G-action-20x:

Okay, I thought my silly questions were taking space on the forum. Sorry I will stop removing them.
But why the wind loading which is acting downwards does not have to be negative, but the gravity load has to be negative?
For unit consistency I use SI units, for the data below:
Density = 2,680 kg/m3
E = 70.7 GPa v = 0.33
Plastic strain = 0.2 Yield stress = 240 MPa,
In ABAQUS, I input these:
Density = 2,680
E = 70.7 x 10^9 v = 0.33
Plastic strain = 0.2 for yield stress = 240 x 10^6
For the loadings (all...
I was able to do the cut through the part. But there was few things that don't match what I wanted.
I wanted the triangular section to cut through the part. However, cut through the entire part. Look hoe the part is cut from down to up. How can I do it properly? My section cut implies only a...
I want to cut a triangular section thru a part at an angle to the face (not perpendicular)
Can you tell how can I do that please?
Here is the line through which I wannna make the cut:
Here is my trial:
1)I drew an axis at the start of the cut, on the face of the part.
2)I make a plane along the...
