Difference between Line Loads and Pressure Loads

Altair Forum User

Hello Everybody,

 

I have a general question. Let's say I have a force of 1000N, which acts on a defined area on my geometry. I have applied this load as a line load on the area but now I am wondering if I am making a mistake not applying the load as a pressure load. Where exactly is the difference? If I know the area, on which the load acts and apply this load as a pressure, it should lead to the same solutions, shouldn't it?

 

I would be very thankful for any help because I am pretty stuck at the moment.

 

Thank you for your help in advance

Hi Dean,

line loads, result from the integration of surface loads along one transverse direction, such as a beam or plate thickness, or of volume loads along two transverse directions, such as a bar or beam area. Line loads are measured in force per unit length.

 

But pressure is measured as force per unit area.

 

If you know the area and apply load (load per unit area) then I think this will have the same solution.
