I am currently working on a project related to bending origami actuator utilizing air pressure. I am confused on why pressure magnitude needs to be defined if I already define the tabular amplitude. What is the use of each (magnitude and amplitude)?
Attached below is the screenshot I taken regarding the magnitude and amplitude.
Thanks in advance.
Hi Samuel Hidajat,
At every increment Abaqus prescribes
current pressure= pressure magnitude *amplitude
Dear Samuel,
Amplitudes allow you to specify arbitrary time or frequency variations of load, displacement throughout a step using step time or throughout an analysis using total time. The amplitude allows you to create and manage amplitudes. For example: it can be a load following a function in analysis step, it can be a load following defined amplitude tabularly, it can be a load with linear incremental behavior, it can be a load that follows an oscillatory behavior in time, etc.
It's like Professor Victor J. Аdlucky said. It is right. The amplitude is the multiplier of the magnitude.
I hope these comments help you.
Best regards,
Jorge
