    Better Resolution of Time

    Dear friends, I am doing a basic impact problem in which a deformable ball (made of Aluminum) is being dropped onto a rigid flat plate from a height under the influence of gravity. My primary aim is to resolve the impact time to the nearest milli-second. My approach to this is by plotting the...

    Excessive Deformation!

    I tried to finely mesh the "hex-can" part so that there would be more than one element through the thickness. No other mesh element is compatible with the "hex-can" part, and hence I could only use tetrahedral elements. I have, therefore tried to modify certain properties of the tetrahedral...

    Excessive Deformation!

    Friends, I am doing a simulation in which a cylindrical rod is being eccentrically dropped into a cylindrical hole with varying diameters. I have defined both the bodies as deformable bodies and also have defined contact wherever necessary. I am getting an error for "15 excessive deformed...

    Modeling in-elastic collision in ABAQUS FEA

    Rob, Thank you so much for your timely reply and help. I had initially done the analysis for the quarter sphere dropping into the plate (Impact analysis) and didn't modify the Step accordingly,it was careless of me. I am also enclosing the CAE file for future reference. Thanks...

    Abaqus error

    Dear dhobleashish, You must have pressed the "Kill" button in the Job Monitor. The SIGTERM is usually a generic signal for program termination, and as suggested it was invoked by external request, aka externally killing the process. Hope it helps you out. Regards

    Modeling in-elastic collision in ABAQUS FEA

    Dear Rob, I was able to do the simulation, but the results are not coinciding with the theoretical values. I am also finding significant interference among the meshes and tried making the slave surface to be more finely meshed, following an advice from PolymerFEA forum. I am attaching my CAE...

    Modeling in-elastic collision in ABAQUS FEA

    ***** UPDATE ******** I have tried my hand in the problem the following way. >Created two bodies, both analytically rigid (one solid sphere and a flat plate). >Provided information regarding materials and created surfaces and assigned surfaces to relevant bodies. >Then imported the bodies into...

    Modeling in-elastic collision in ABAQUS FEA

    Hello! I am trying to model an inelastic collision of a ball into a rigid flat surface. I am trying to model the most basic of examples to obtain the coefficient of restitution. I am also neglecting the force due to gravity on the ball. For my initial analysis I am planning to model a normal...
