      Hi,


      I am using ansys explicit to solve impact analysis of metallic sphere on metallic sphere, I want to give initial temperature to entire body or temperature gradient in body, please help me how to do this ?


       


      Thanks

      Hi Nand,


      What is the objective of giving initial temperature? The body has is prestressed due to temperature load. You may run a static structural analysis in which temperature load is supported and then import results to explicit dynamics (prestressed explicit dynamics).

      thanks I will try this.

      I am trying to simulate cold spray of metallic particle on metallic substrate in which particle will have temperature as well as velocity.

      Hi Kcao,


      this will not solve my problem because in explicit for taking consideration of high strain rate I am using J-C material mode which is not supported in static structural analysis.


      any other suggestion ?


      for clarity I am explaining my problem:


      I am doing cold spraying simulation of metallic particle on metallic body. now metallic particle will have temperature and velocity during impact, and this whole process involves very high strain rate so I am using JC- material problem. Now, my problem is how to give different initial temperature to particle.
