    Hill 1948 Yield Criterion

    Thank you Btrueblood for your response. From your advice I have answered my own question and recognised that some of my initial assumptions are incorrect.

    Hill 1948 Yield Criterion

    Thank you btrueblood for your reply. Yes, I am aware of those links. My question more specifically is can L,N,M be defined by solely r-values (lankford coefficients) as F,H and G can? Best Regards, HW

    Hill 1948 Yield Criterion

    Many of you, I am sure, use Von Mises as a yield criterion to calculate the equivalent stress and strain on your system. I am using Hill 1948 as it provides an anisotropic analysis. However, I am having trouble calibrating Hill48 using the r-values. Hill constants F,G,H are requal to r0, r90...

    FEM-Stiffness matrix

    Hi everyone, I am very new to the FEM. I have been doing some basic linear analysis using the COSMOS application within Solidworks. However, I find my colleagues accept the post-processed results as the 'truth'. I am not saying I don't believe it's output but I am from a more traditional...

    Fortran Format command

    Thank you Johnhors! That is my problem solved. Is the 2 in the statement 200 Format (2(A,F15.2)) because I have two variables, x1 and x2? Thanks again

    Fortran Format command

    Hi guys, Thanks for your help. I have tried both methods but with no success. Basically I am getting a four decimal place output when I am trying to specify a 2 decimal place. I have attached the two methods that were suggested. As far as I can see that is the method to format an output...

    Fortran Format command

    Hi, I am having difficulty using the FORMAT statement to output numbers to a specified number of decimal places. The program is stated below and is a simple quadratic equation calculator. If someone can help me it would be a great help. Thanks in advance. HW PROGRAM OOV2 IMPLICIT NONE...

    Sequential Pneumatic Circuits

    Hi guys, I would really appreciate some help on this one. I am trying to update a circuit from a cascade design to a one out of n sequential logic design. I have successfully created a 2 out of n but in keeping with the rest of the drill I would like it to be 1 out of n. I have attached my...

    Plotting a range of data

    Looks like that has half worked! As I imported my data from a spreadsheet it hasn't appeared due to the link breaking. However, the equations are correct so a quick manual entry of a couple of lines of data would work. If you know any other way to import the data permantently please let me...

    Plotting a range of data

    Thanks, I done that and the link should be included in this post.http://files.engineering.com/getfile.aspx?folder=2b670210-516f-46e7-87ff-01d73cda0b5f&file=stress-strain.xmcd

    Plotting a range of data

    Thanks for the reply excognito. I uploaded the file to Engineering.com but I don't think I done it right. Can you provide me any guidance on how to upload on this site? Thanks for the support.

    Plotting a range of data

    Hi everyone, I am new to Mathcad so please bear with me. I am trying to plot a scatter of two variables. This works fine, however when I specify a range for the two vectors it does not work. The error message stating "Value must be a scalar" in regard to the range value. Can anyone help...
