In the "Edit Load" section in Abaqus, I saw the "Magnitude" value, so how do I get the value of it with Load: Sigma = 1MPa? Does it have any formula to it?
you can directly set the value of "Magnitude" to 1MPa. There is no specific formula involved in this case as it is a direct assignment of the desired load value.
Long Le, there are two ways to control pressure with amplitude in Abaqus:
Direct Pressure: Specify the pressure value directly in the load definition. This is suitable if you want a constant pressure throughout the analysis.
Amplitude Control: Define a separate amplitude curve to control the pressure variation over time. Then, in the load definition, reference this amplitude and specify a pressure value (1 MPa in this case). This pressure value acts as a scaling factor.
Important Note: The amplitude value itself should be between 0 and 1 (inclusive). A value greater than 1 will result in a pressure exceeding 1 MPa because Abaqus calculates the final pressure as: time x amplitude x pressure.
