    Bulk Vs Foam Stress-Strain ?

    Hello FEA way Thanks for your response. In regard to your Questions: Question-1) So it’s a random pore distribution and only the porosity level is the same as in the experiment ? Answer-1) Yes, It's random, and its ratio of porosity is the same as experimental. Question-2) The material data...

    Bulk Vs Foam Stress-Strain ?

    Hello everybody I'm Working on Representative Volume Elementary (RVE) of Aluminum Foam. I generated the Geometry of a foam with %50 porosity. The main goal is to mimic the experimental Stress-Strain Curve and get the same response of foam that was achieved in reality. Therefore, different...

    Abaqus Force Displacement Curve Not Smooth

    Hello Struct123ure I did not run your model, But i think it's related to your contact definition. Maybe when your model experience Crack/Element deletion, Between your components (Rigid and Deformable) some sort of gap and discrepancy happened. Check is there any gap or deviation happened...

    Simple Structure Optimization get Twisted ...

    Also in optimization process the amount of Reduction that I done is in accordance with the paper framework, But Results they show is significantly different what it should be ?! Paper framework for Optimization: What I get from this kind of configuration: What paper Show as Result: So Confusing !

    Simple Structure Optimization get Twisted ...

    FEA way, Thnx four your respond. Yes Indeed, And also i did the same thing in my simulation. But sadly the output is not the same as The source paper demostrated. Source paper: What I done: As can seen The amount of the Stress and Deformation did not match. On the other hand Reaction forces...

    Simple Structure Optimization get Twisted ...

    Hello everybody. I'm working on simple structure from a paper, "On the topological optimization of horizontal links in eccentrically braced frames", That need to be validated. So far, I think done all steps according to the source paper but still there is something fishy that I can't figured...

    Projected/Active area Between Connecting rod and Crankshaft ?

    Hi everybody When the Engine working, Connecting rod Transfer Load from Piston to the Crankshaft. So We can Calculate That load from P-theta Data. Now if we want to calculate the Pressure of that Load on Crankshaft, We need the Projected/Active area Between Connecting rod and Crankshaft. And...

    Parallel execution in Abaqus/Standard

    FEA way Thanks For your response. Also I have another Question: If There is no Domain decomposition, Then how Software use Parallelization in Job module (I read "Parallel execution in Abaqus/Standard" But I can't find anything useful to my question) ? BTW, This is the error full massage: With...

    Parallel execution in Abaqus/Standard

    Hi everyone Fast Question: 1_Is there any Domain decomposition in ABAQUS/Standard (For example: Static General) ? 1-1_IF The answer is YES, Why i get this error with regard of activation of Parallel execution (14 Processors) "This model is too large to run on a single domain. The number of...

    Gantry-Crane with Pin Joints ?

    Now If I don't want to divide the frame into 3 parts, Is there any options to separate One common Node (Red Node) To two separate nodes ?

    Gantry-Crane with Pin Joints ?

    Hi FEA way Thanks for Reply. My whole model is one part (not separated parts), Therefore there is no 2 nodes between 2 wires, it's just a common Node (Red node) between them. Same before, There is no 2 Nodes, It's one common Node, If there is 2 Node then can you explain more? Same Problem...

    Gantry-Crane with Pin Joints ?

    Hi guys I Simulated something like the below Image. With Wire features (Like Below): Now I want this two Red Node act like a pin joint: Like This Kind of Joint: How Can I Do That ? With Best Regards. yassou.

    Absorbed Energy

    Hi everybody I'am simulating Cylindrical composite with external force or blunt impact. My material is Fiberglass-epoxy with fail stress. And my simulation method is Dynamic explicit. Now my question is: How could i know the amount of energy this composite absorbed from that impact or force...

    Small Faces

    Hi dear LWolf Thanks for your respond. Can you explain more about the try to align your sections with guide curves, i.e manual connection. ? I know how to create guide curves, but i did not hear anything about manual connection. With Best Regards. yassou.

    Small Faces

    Hi dear weagan22 Thanks for your respond. Indeed you are right, I tried the Curve Smooth and extra/redundant vertices removed. but other problem raised. Now Multi Section Surface did not work. maybe the Sketch get too simplified and i think there is not enough vertices in Sketch to get connected...

    Small Faces

    Hi dear FEA way Thanks for your respond. Indeed you are right, I tried the Geometry edit” tools - „Replace faces” with („Extend neighboring faces” on) or „Repair small faces”. But none of them did not solve this problem because they change the geometry of the model significantly or in some area...

    Small Faces

    Hello Everybody I have a problem. I want to simulate human rib bone in Abaqus Software, so i take this steps: Catia Software=>Sketch tracer=>Draw Sections from CT image=>Extract Closed Curve=>Multi Sections Surface=>Closed Surface=>Multi Sections Solid (Picture 1,2)=>Save .stp File=>Import in...

    Questions in Heat transfer simulation

    Hi everybody I have some questions in Heat transfer simulations and I will be appreciate to anyone to answer them. 1)In Property Module, Why we should define the Density? 2)In Heat-Transfer simulation with Transient Response, In Step Module, Can we give the Large enough amount of time (For...
