    Abaqus modelling

    There are dedicated material models for concrete in Abaqus and many resources to find inputs for them. Linear elasticity is only valid for small strains and materials that exhibit purely elastic deformation from the beginning.

    Post-buckling of Beams

    Well, this is very different software and we don't know the MATLAB code you are using. Is the setup (boundary conditions, loads, imperfections and so on) exactly the same ? Most likely element formulation and nonlinear solver differ a lot.

    How to determine G12 if I have E1, E2 and v12?

    Check this thread: https://www.eng-tips.com/threads/calculation-of-shear-modulus.295070/ SolidWorks uses G_xy = (E_x*E_y)/(E_x+E_y+2*E_y*v_xy) if you don’t specify the shear modulus.

    Hinge Interconnection Not Working – Only One Shell Part Moves

    Can't you apply the prescribed displacement differently ? Maybe push the plates with a rigid surface ? But yes - please share the .cae file if possible.
  5. FEA way

    Singularities appear only when beam/pipe is inclined – PIPE31 element

    There's no file attached. Can you try sharing it again ? Numerical singularity warnings typically indicate underconstraint (unconstrained rigid body motions).

    Need help modeling an elastomeric laminated bearing

    Yes, rotational DOFs are not constrained when shells or beams are embedded in solids. But it's still probably the best way to model such reinforcements. Unless you want to e.g. account for delamination.
  7. FEA way

    Shell to shell constrains

    Can you share a screenshot or at least rough drawing of your model ? Such connections are usually achieved with tie constraints or contact.
  8. FEA way

    Need help modeling an elastomeric laminated bearing

    Then you can use the embedded region constraint. This way, you won't need cutouts in the rubber for steel plates.

    Applying Local Coordinate System for BC in Abaqus

    Yes, the workflow is correct. Here’s what you can check: - local X displacement values - are they significant or numerical zeros ? - is the local CSYS displayed as you want it to be oriented ? - is there a *TRANSFORM keyword in the input file ? - what if you run a frequency analysis and examine...

    Why does the electrical potential not go the way I wanted?

    If you don't want the electrical potential to transfer from the circuit to the plate, you can also disable that DOF in tie constraint: *TIE, NO ELECTRIC POTENTIAL This way the tie constraint will only provide mechanical (and thermal if applicable) connection.

    ECAP - material flows between the punch and the die?

    Make sure that the proper side of the punch bottom surface is selected. Try adding some point mass/inertia to the rigid body reference point. You should also consider replacing discrete rigid bodies with analytical rigid surfaces whenever possible. Check the energy outputs (especially ALLKE and...

    Why does the electrical potential not go the way I wanted?

    Can you provide more details ? What are the boundary conditions ? What materials are used for each region ? How are the regions connected (any tie constraints or electrical contact) ?

    Abaqus Metallurgical phase transformations simulation example running problem

    From the 3DS Software Downloads page but you have to log in using your customer account and then you will find the software available to you. Look for Abaqus, you will see the most recent fix pack files by default. Installation is very simple, you just have to click Next after unpacking and...

    Abaqus Metallurgical phase transformations simulation example running problem

    You have to install a fix pack for Abaqus 2025 to make it work. Possibly the newest one (HF3) but the USER TYPE parameter was introduced in Abaqus 2025 HF2. Alternatively, you can use the old syntax: *MATERIAL, NAME=ABQ_PHASE_TRANS_TI6AL4V

    Abaqus Metallurgical phase transformations simulation example running problem

    What version of Abaqus are you using ? Is that a student version (Learning Edition) ? It may not work then.
  16. FEA way

    Hinge Interconnection Not Working – Only One Shell Part Moves

    Try with edges selected for coupling constraints instead of the whole plates.
  17. FEA way

    Material units

    Consistent commonly used SI(mm) units are: - Young’s modulus [MPa] - density [tonne/mm^3] - thermal conductivity [mW/mm*K] - specific heat [mJ/tonne*K] If you search for "Abaqus units" you will find some helpful tables with other consistent unit systems.
  18. FEA way

    Hinge Interconnection Not Working – Only One Shell Part Moves

    Did you attach those reference points to the plates ? You can do that via rigid body or coupling constraint.
  19. FEA way

    Excessive Distortion in Press Hardening Simulation

    You should always check the warnings. Here you have unconnected regions, negative eigenvalues and numerical singularity messages. Check the nodes where issues occur. You can use the Job Diagnostics tool to highlight them. This is easier than reading plain .msg files. Another way is to upload...

    Interface fracture mechanics - Why isn't ENRRT11 = GI?

    How far are they ? Is it Abaqus/Standard or Explicit ? Are you using viscous regularization ? Did you check the standard energy outputs (especially ALLSD and ALLVD vs ALLSE) ?
