Hi all.
I'm simulating drilling into a sandstone SPG ram.

Drill - MAT_PLASTIC_KINEMATIC, sandstone - MOHR_COULUMB.

The units I use are: GPa, ms, kg, mm.

I use explicit analysis and the following settings: 

I indicated the initial temperature in Celsius 22 degrees, is this correct or should it be indicated in Kelvin?

I waited for two entries in the d3plot and saw that the temperature on the SPG particle plate was very high, why?

 

Temperature graph on an SPG slab:

And how can this be fixed? Maybe you need thermal expansion cards?

Hi

Can you let us know the solver used ?

Cheers.

I use explicit analysis.

Version of the solver from the Ansys 2023 R1 package.

Guys, I carried out an analysis when the drill passed through the SPG die and this is what happened:

The temperature at the SPG slag is very high. Why? How to deal with this?
