    Axial + Hinge Connectors / Displacement Issues

    Hello FEA way ! First off, thanks for your reply! The hinge connector is connected to the ground, so the wire is not shown. The same point is used as point "a" in the axial connector as a center pivot. Please refer to the following picture: Regards

    Axial + Hinge Connectors / Displacement Issues

    Hello, I'm trying to simulate a mechanism on which I have two movements as follows: 1. Linear Movement in U1 through an Axial Connector. 2. Angular Movement in U1 through a Hinge Connector. Steps Step 1 ------------------- Movement 1. -3 inches- Step 2 ------------------- Movement 2...

    Pvc Pipe Local Buckling due Internal Pressure

    Hi Gents, I’m machinery designer for the PVC pipe Industry, at the very beginning of this year I designed and built a Machinery to test PVC pressure pipe according to AWWAC900/05 and (or) FM Standards. My customer is request me, and special test called Burst -the pressure rate depends on the...

    4C900 PVC Pipe Buckling during Testing

    Hi Gents, I’m a machinery designer for the PVC Pipe Industry, few months ago I was involved to design a Hydrostatic Pipe Tester according to AWWA C900/5 or FM Standard. One of the special features requested by my customer was “Quick-Burst” capability using a whole pipe -6.1m / 20ft long- as a...

    TRANSIENT PIPE COOLING FEA

    Corus, I really appreciate your help, I'm agree with your FEA statement. But @ this time I wanna to simplify the model as far as I can, so that's my idea to keep steady the pipe and axisymetric, and try to move the jet cool nozzle (s) in the axial direction, to cool down pipe, what is not...

    TRANSIENT PIPE COOLING FEA

    Dear All, I need to figure out how can I set up this FEA, I wanna simulate a plastic pipe cooling process in a extrusion line, so basically, I have a water cooling nozzles over the surface of the pipe, they're fixed in a frame, and the pipe goes in a constant velocity passing for all the water...

    Steady state heating pipe + Transient cooling

    Hi guys, Im stucked trying to model a very simple FEA, I need to heat up a pvc pipe applying air convection load, to find time needed to. I did and steady state axisymetric model, and apply a Surface Film and initial temperature by a predefined condition, but looks like the temperature never...

    carbon fiber lining

    Hi, Thanks for clarify but, can you tell me how can I be able to select a skin, in order to assign composite shell properties, because when I tried, abaqus cant let me do that. Regards Pablo

    carbon fiber lining

    Dear colleagues; Im trying to simulate a steel tube reinforced with carbon fiber linings but im stuck how can i tie shell with ccontinun elements; or how can u simulate it in the right way! Pablo

    Huge Deformation on Sharp Indentation

    Dear All, Im trying to get the force needed to penetrate a PP (elasto-plastic) tube with a sharp tooth -rigid surface-, using ALE, but cant get results,instead I get huge mesh distortion. Anny suggestions? Regards LPUS...

    Wrapping Steel tube with Carbon Fiber laminates

    Dear All, This is my first approach to model a steel tube-like wrapped with carbon fiber laminates, exactly I don't know how can I orient the fiber layups into cylindrical coordinated system, what are the steps I need to consider, and how I tied between steel and carbon fiber. Apologize me if...

    *SYMMETRIC RESULTS TRANSFER

    Hi, I'm running axisymetric contact analysis, 3 deformable parts, one of them hyperelastic, but right now i wanna transfer the results into another 3d new analyis to apply non axisymetric loads. I know that abaqus manual says, thats no possible to transfer results from assembly instances...

    Clip-spring insertion

    Hi DanStro, Thanks for the sggestions job running, you're right the groove will be reached at 6.5mm not 6.0mm as I put in the prescribed displacement. I'll try also in the explicit way Reagards Pablo

    Clip-spring insertion

    curlyq / rstupplebeen, Thanks a lots for the time you took to read it, I also think same as you, rigth now I'm trying to run it into Explicit. I'll keep you informed Best Regards

    Clip-spring insertion

    Dear friends, I’m trying to do very basics, insertion analysis of a ring in to a shaft groove, via prescribed displacement conditions to know the force required, but until the ring reaches the grove the job is aborted by a classic convergence problem, “ Time increment required is less than the...

    DMTA and Prony Series

    Hello all, Modelling a pipe-end socket thermoforming-like simulation of PVC I been found a lot of problems, exactly that I try to do is this: http://www.youtube.com/watch?v=vDW4tSda_0U I have DMTA test results E' and E'' against time and temperature sweep. The question is how EXACTLY do I...

    thermoforming of a PVC pipe socket

    Good Morning Dear team. Right now I’m experiencing troubles with an FEA Abaqus analysis about the thermoforming of a PVC pipe socket. Let me try to explain you in detail: The Rieber socket forming system enables thermoforming of sockets with integrated gaskets. Rieber elastomeric gaskets are...
