I am currently simulating Bullet impact on a Aluminum 5083 Plate. The problem that I am facing is that the model works fine when the thickness of aluminum plate is 20 mm or under. It starts behaving strangely when the thickness is increased. If the thickness is increased, d5 has to be reduced so...
Hi. I am working on ballistic impact on Aluminum 7017. I am facing an issue that if I give the value of Temperature in "Pre-defined Fields", the material is not removed properly. But if I don't give the value of the temperate, the model seems to work just fine.
I wanted to ask that is the...
Hi Everyone. I am facing a strange problem. Bullet material is Steel and the Metal Plate is AL-7017. I have turned on the "STATUS" from Field Output and also written that INTERIOR thingy with the respective sets before *END ASSEMBLY. The problem is that the job starts, for a few millimeters the...
What is meant by the term "FS" in the material definition of a ceramic (Silicon Carbide in this case) under Johnson Holmquist Damage(JH-2) Model of JHB Model? Screenshot is also attached with it. http://files.engineering.com/getfile.aspx?folder=2c178e21-699f-4daa-8345-cbcec1c4139b&file=JH2.JPG
I am working on a high speed impact on 99.5 % Alumina using JHB model. Is there any research paper of link from where I could find the JHB model constants for 99.5 % Alumina?? All I could find were JH-2 parameters.
I am working on bullet impact on ceramics. Materials are ABQ_JHB_siliconCarbide and Gold. I also performed this on the Aluminum and Steel (Tech. Brief) and used this procedure in that model and it worked perfectly.
