    mass decomposition vs pressure increase

    Thanks Blonde for your useful post. i used a fortran subroutine to simulate the reaction rate, and with this routine i have calculated the fraction of energetic material that have beeen decomposed (from 1 to 0) at each node. to simulate the pressure increase i suppose that i have to calculate...

    mass decomposition vs pressure increase

    Hi MintJulep (Mechanical, Thanks for your email, but i'm trying to simulate this on abaqus. as i have said, i have done a thermal simulation and i have temperature and mass decomposition profiles (as results). But i would like to make a thermal-stress displacement simulation, and i don't know...

    mass decomposition vs pressure increase

    Hi, I have the following problem: i have a closed tube that was heated at 3.3ºC/h, and it has a energetic material inside. so i have obtained the temperature and the mass decomposition profiles for this energetic material. but i'd like to obtain the pressure increase inside this tube. Does...

    how to use thermal and pressure information in a subsequent analysis

    Hi, i have performed a Uncoupled heat transfer analysis about a cylinder with a material inside that decomposes along temperature increase. the results are: nodal temperature distribution mass decomposition local pressure now i'm trying to perform a simulation about mechanical deformation on...

    user subroutine

    hi, i was using abaqus 5.8.4 with user subroutine hetval, and i have no problems. now i'm trying to run previous jobs on abaqus 6.2.1, but i have some problems with user subroutine. the message file shows "subroutine hetval is missing". can anybody tell me what's wrong?
