Single Shot particle Impact analysis using ABAQUS

[sapta1754]

Dear all,

I am performing a Contact mechanics problem.In which I am not able to simulate the problem.It would be kind of you if you could help me with this.

I tried a lot of ways to perform but still I could not do it.
It would be really really kind of you if you could help me with this.
I have attached the .cae file.

Thank You

You're not likely to get a lot of help asking in the manner that you are asking. When looking for help, it's necessary to put more explanation into your problem than the person who is going to respond with advice. In this case, there isn't any mention of material properties, goals of the analysis, past attempts, assumptions made, and results/errors that have been achieved.

If your looking for someone to do your work for you, it's doubtful you will find it. Not for free anyway. If you want to try to put in some serious effort, I'm sure you'll get some good responses from the helpful folks on this forum.

I am extremely sorry for not clarifying myself,

I am designing a model of shot peening with a single shot.
I want to see the deformation caused by the particle when the shot interact with the target.
I have designed and analysed many a times but I am always getting an error of element getting distorted,and the ratio of the deformation speed exceed 1.0000 in at least one element.

I have attached the new .cae and the .inp files.

I don't have a ton of experience with this particular analysis. My initial thoughts would be that you don't have a fine enough mesh at the area where contact occurs on both components. Additionally, you may be using the wrong type of elements to perform this analysis.

I don't have much specific to add, except that you should use the theory manual to look for any similar types of contact problems that you can find. Be really thorough in looking through that and compare to what you have.
