AI Thread Summary
The discussion focuses on demonstrating material nonlinearity due to temperature changes using ANSYS. The user is struggling to set a specific temperature in their model, despite having commands for material properties. They attempted to use the command "da,1,TEMP,50" but observed no effect. Other participants suggest that using ANSYS Workbench could simplify the process and provide a tutorial link for setting a default temperature. The conversation emphasizes the importance of correctly assigning temperature to illustrate the relationship between force, stress, and strain in the model.

I have one small question. I'm trying to demonstrate material non linearity due to temperature.
In other words, I want to show that for the same force, the stresses in the material may be different due to the temperature of the object. Now, I figured the commands for the material properties part, but what I can't figure out is how I set my model to have a specific temperature. I tried using the da command (eg: da,1,TEMP,50) but it showed no effects whatsoever.

Do you have any tips for me?
Thank you for your time, much appreciated.

Isn't the fact that temperature-dependent material properties tables exist proof enough? ANSYS can only show what has been put into it in the first place, so solving a temperature dependent model into it doesn't "prove" anything...
 
thats true :) maybe i used the wrong word there... i want to demonstrate how it works, is that more clear?
 
Unfortunately this assignment we had to use the APDL script. For the material properties, the script was relatively simple:

MPTEMP,1,0,700
MP,EX,1,12E6,-8E3
TB,BKIN,1,2
TBTEMP,0.0
TBDATA,1,44E3,1.5E6
TBTEMP,700
TBDATA,1,29.33E3,2E6
/XRANGE,0,0.02
TBPLOT,BKIN,1

now, for a simple model I'm trying to demonstrate that for the same force and different temperatures the strain vary. What I'm not able to do is assign the model a given temperature.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Calculate minimum RPM to self-balance a CMG on two legs'
Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
