hi everyone
can anybody pleases tell me if i can draw a complex shape in other programs (e.g. autocad) and then import it to abaqus.
i don`t know how to draw a complex shape directly via abaqus.
thanks
I would like to calculate maxim safe size of delamination in composites using ansys/abacus.
I went through the forums here found that cohesive zone modeling & vcct techniques are being used only in ABACUS. Is it not possible in ANSYS APDL?
If not please can somebody provide me tutorial of ABACUS regarding interfacial cracks. Also which one better VCCT or Cohesive zone modeling for an existing crack.
Regards.
I've build a 2D dimensional model of hydraulic fracturing based on the example on Verification Manual. I use the same data from the example. I build the model in CAE and edit it in input file to add cohesive element and cflow. however, the simulation stoped after 10 minutes indicating that a erro:"THE CRITICAL FRACTURE ENERGY IS SMALLER THAN THE ELASTIC ENERGY PRIOR TO DAMAGE INITIATION. THE DATA MIGHT NOT BE SPECIFIED CORRECTLY FOR *DAMAGE INITIATION OR *DAMAGE EVOLUTION.
Is it possible to use a Johnson-Cook method to predict the fiber damage in a composite lamina? I am presently using ABAQUS for it. I want to capture fiber failure.
Hi all,
Recently, I have read the paper "Dynamic crack propagation under mixed-mode loading- Comparison between experiments and X-FEM simulations" published in IJSS, 44 (2007), 6517-6534. I have met some questions on the choice of auxiliary fields for calculating the SIFs. Could someone give me some details including the auxiliary velocity fields, the auxiliary displacement fields and the auxiliary stress fields. Thanks.
regards
Hi
During my thesis I am calculating mode 1 stress intensity factors (J-integral) for inner crack in pressurized thick-walled cylinders with ANSYS v13.
The loads are inner pressure on the cylinder bore and gas pressure directly on the crack plane.
I wanted to know why the J-Integral converge along part of the crack front (from the deepest point Phi=90 until Phi=60 degrees, assuming semi-circular crack) when loading the crack plane directly while with the inner pressure the J-integral converge along the whole crack path.
Best regards
Hello all,
After performing an analysis step, could I remove an element from the mesh grid(thus, creating a geometrical change in the model) and then run another analsyis step? Is there anyway for ABAQUS to do this without me physically removing the element?
Thanks
