Assignment 4-RADIOSS Material Laws Challenge
(1.)
aim: studying the changes upon change in properties of a rupture plate.
procedure:
1. The chp1.rad input file is impoted into the interface of the hypermesh. The card propoerties set as per required.
2.The analysis of the condition is done using radioss solver and the animation files along with the details from the solver are obtained.
3.The h3d file of it is the opened in the hyperview in the second view. and the countours are then plotted .
4.The stress is averaged and the animation ios palyed and the values are observed.
5.The failure_jhonson results then compared with the law27 and law 2 in similar mannner and thus the observations noted.
results:
The countiurs in the above cases are different and the max values of stress obtained and the energy plots are diufferent depending on the material properties.
the values are recorded and shots of it are taken.
(2.)
aim: Obtaining Johnson cook material application results.
procedure:
1.Import the model inpit file and run it on the name law2_espmax_failure.
2.The files will get genrated in the location as set during the radioss solver operation and are stored there. these can be overwritten upon change of values further.
3.In the failure jhonson change the values of ifail_sh=1, and ifxem=1.
4.Then run the model using the radioss solver named as law2_espamx_carck.The values will be overwrtten in the same folder. or else can create a destination.
5.Then deleting the card and run this as law2_espmax_nofail.
6.Then delete the EPS_P_max an run the modelas law_2.
7. Concvert it to law1 and then check the results.
results:
The results obtained are then noted down and the chnages are the seen in the obtained folders upon importing. thos creates different cases using the laws.
(3.)
aim: Application of plasr_BRIT materail.
procedure:
1.Open law27 input file by importing it to the hypermesh interface.
2. Then running the radioss solver to obtain the solved solutions.
3.The shell properties are then changed and run using the radioss solver.
4.The jhonson cook failure card is applied with cahnge in the eps based parameters. and then it is run in the solver on name of law27.
results:
the obtained results are taken a shot and noted.we can thus see the change innthe entire folders.
