Title: Problem with the values of stress obtained
Post by: Esteban Opazo V on May 19, 2017, 10:53:26 am

Dear, I have a problem with the result of the program.

I could have a problem in boundary conditions, I don't know. The problem is the following:

I define the strata and the applied load, as shown in the following figure:

The program gives the following result:

The problem is that the area of greatest stress (blue zone) is on the surface and not under load. Also in this area (under the load) very low efforts (stress) are obtained (red color), the opposite of what should be.

I hope you can help me. I'm just learning to use the software.

Greetings and thanks in advance

Esteban,

please keep in mind that based on the sign convention (specified in the help manual) in the program the negative number indicates compression (and positive value tension). so red color has the largest compression stress and blue color has the less compression stress which makes totally sense.

overall the contour plot looks reasonably correct to me.
