Thank you so much ... It works Really appreciate your help.

Hello, I am working on ANSYS Mechanical (APDL) .. the one that has a black background... I have changed the background color to white because I want to print them by printer and do not want all that blackness to be in the paper .. the problem is: the contour value texts is originally white...

@ Hacksaw Thank you again your tips reflects your background of knowledge. I wil do it as you said.

@ Vibac I already downloaded the paper , it is really useful. thank you

Hello All, I am using ANSYS to simulate the lateral vibration of a rectangular plate. I have a simple case. I modeled the plate and entered the material properties and Meshed it. I want to put on one of the nodes a Sinusoidal load of the form: F(t)=50*sin(10*t) Then choosing a certain time...

Thank you, To be honest I could not get the book !! Is there any other reference?

Hello Hacksaw, Thank you for the information. Do you mean the text "Finite Element Modeling: In Engineering Practice" For Constantine C. Spyrakos ??? because i did not find any thing else for him in books.google.com Thank you

Thank you So much prof. I do understand now. one more question please. Is there any reference talking about this issue ??? maybe I can find some tables or figures concerning this problem. Best Ghazwan

Hello Dr Michael , Thank you for your response. I have three boundary conditions (4-edge clamped, 3-edge clamped, 2-edge clamped). The material is basically Steel (Poison's ratio=0.3,E=200Gpa). The plate is simple thin plate only. Is it any way to calculate the constants using the formula...

Hello All; I am working in the vibration analysis field , both theoretical and practical fields. while working in the theoretical side I needed the Rayleigh Damping Coefficients of a vibrating plate.... I need to calculate (Alpha) and (Beta) of the following equation: [C]=Beta*[K]+Alpha*[M]...
