Hello, Thank you for recommending the paper, I will check it out. For calculation I created a reference Point RP1 on the top surface and used the coupling constraint for the top surface and the RP1. in history output I chose to calculate the Reaction force 2 (RF2) at the reference point. So...

Hello @SWComposites, I was able to run the simulation and get the values as follows RF2 at RP1 (F)= 520.759N Displacement at RP1 (D)= 2mm Length of lattice (L)= 6.7mm Area of the Square (A)= 6.7*6.7=44.89mm^2 therefore stress/strain = (520.759N/44.89mm^2)/(2mm/6.7mm)= 11.600/0.289 = 40.13...

Hello, Thank you for your suggestion. I will try the procedure you mentioned and update you with the answers. in the meantime PFA the 2 papers in literature from which I am referring parameters and resulting values 1) Comparative evaluation of printability and compression properties of...

@SWcomposites thank you for your suggestion. I have a few questions regarding it. What will be the cross section area with respect to my geometry. I am applying a fixed displacement so that I get convergence as when I applied pressure to the top surface it was not converging. In which plane...

For getting the 3.5 GPa In XY data- ODB field output- position = centroid Identifiers = Logarithmic Strain Components (LE) - LE22 Stress components (S)- S22 In the elements and nodes tab method- Element Set- all elements I click on save as and average values. then in...

I am using the LE22 and S22 components of stress and strain. I am selecting the entire model and taking the average of the values at each increment. I have double-checked the input values units. Geometry is in mm, E is in MPa v is unitless. displacement in mm.

I want to do it in FEA analysis in abaqus not as experimental.

"how can I calculate the stiffness of this structure?" Isn't that what you are asking when you ask about Young's modulus YES. But I have also read youngs modulus is the material property and Stiffness considers the geometry effect. That is why I asked the question. I am confused about this...

Also, how can I calculate the stiffness of this structure? Thanks

Yes, I calculated using that method. My values are around 3.5 GPa but according to the literature the values for such lattice structure should be within the range of 350-600 MPa. Thanks

Hello, I am simulating a compression test on a gyroid lattice structure in abaqus cae. The geometry has solid surfaces on top and bottom and in between there is a gyroid lattice structure. The model is 10 mm in LXBXH.I applied a displacement of 2 mm on the top surface and fixed the bottom plate...

Thank you

Hello FEA way, Coup you share with me the .inp file of the material verification you did? Thanks, Kunal

I exported it in excel and and calculated the the slope of the linear region @FEA way

Also which stress should I select from the window option in field output when you say gauge section stress in your previous reply? In an actual test, we apply load at the top surface at a specific rate and the bottom plate is fixed. we get the stress and strain graph and the slope of the...

Hello, Thank you for your response. I am still a little confused by how you are asking me to calculate the elastic modulus. Is there a video link or something I could look at to find the modulus that you could share with me? Thanks, Kunal

Hello, I am trying to simulate a compression test according to ASTM D695 standard. I created a part which is a cylinder (r=6.35mm and h=25.4mm). The material properties I applied are for PEEK polymer. They are as follows: Elastic Properties E= 2600 MPa and v=0.378 Plastic Properties Plastic...
