I suggest to define the material properties of the soil as a function of a parameter like x in a way that when you have x=1 it is real properties of soil and when it is 0.5 the properties of the soil is reduced for 50 percent (it should not necessarily be a linear change) . in such way you can say that by changing this parameter you are simulating the soil removal. then you can change this parameter in any way you wish and study the effect of soil removal.

there are several ways to do this. using partitioning you can create a thin layer (partition) on your tool to represent the coating then assign a proper material section with your coating properties to it. Or you can define a coordinate system on you tool (if the geometry is not too complicated) and define the properties e.g. thermal conductivity as a function of coordinate.

hi,
you can find tutorials for both cases on www.helpmewithAbaqus.com

if you question is how to include new surfaces into the contact model, I think you wont have any problem for that if you use general contact model.

hi,
it depends if you are doing the simulation in Abaqus standard or explicit. If it is standard there is no way as time does not have any meaning. if it is explicit then you just need to define a new step with your desired time length for which you want to hold the punch. In any case it your material properties are not rate dependent and you dont have bauschinger effect I guess holding time will not change anything.
thanks,

hello, i simulate the problem of springback in U beding process, please i want to see the effect of the hold time of the punch on springback, can you help me how do that, it means how to put the punch on the blanc for a defined time then remove the punch.

While doing excavation analysis of tunnel ( plane strange) in abaqus, I need to create a contact surface on excavated boundaries. In my model, first I gave initial loading, then run first step as geostatic and created equilibrium and subsquently I used static general and also deactived the surface where I need excavation boundaries by model change.further I need to create a contact surface on the excavated boundaries. Please some one help.

Open a new thread / tutorial for Modeling a Nozzle and Pressure vessel

Hi,

can anyone make a tutorial video for modeling a Pressure vessel and a Nozzle on it?
also that would be great if there is a way to show how to model the welding between Nozzle and shell.

Regards,

I am trying to simulate temperature distribution in the turning operation for that I am planning to consider the coating on the cutting tool so can anyone help me out how can I model a tool with a thin coating on it. I have all the properties of the tool and the coating.
