Roland Schwarz Dec 5, 2015 4:05 PM (in response to Deajn Dejanovic)What is different besides the use of scientific notation on one scale and full numbers on the other?

Deajn Dejanovic Dec 6, 2015 3:32 AM (in response to Roland Schwarz)Both Static solution has load 20kn
Capture1 screen show max Von Mises 51, so 235/51=4. So I can still rais up load for around 4 times.
Capture2 screen show max Von Mises 5.175e. So I have already exceeded load for around 2 times.
And, in real world I think beam HEB180 can able to hold much more then show Capture3, around 9kn!

Jody Byram Dec 7, 2015 5:19 PM (in response to Deajn Dejanovic)Capture 1 shows Von Mises stress max of 51,754,848, or 5.176e+007 (e+007 means move decimal point 7 places to the right)
Capture 2 shows Von Mises stress max of 5.175e+007, which is the practically the same.
Count the decimals carefully, and you will see. Note that the circled values in Captures 3 and 4 are not close to being equal, since one is e+007 and one is e+008, which means one is 10X the other.

Mikael Martinsson Dec 8, 2015 1:35 AM (in response to Deajn Dejanovic)I don't follow, what is the problem?
The only difference between Capture1 and Capture2 is that Capture2 uses scientific notation and Capture1 uses floating notation.
Capture2: 5.175e+007 = 51 750 000 N/m^2
Capture1: 51 754 848 N/m^2
Yield strength of material: 235 000 000 N/m^2 (2.350e+008) so about 4,5 times higher than your calculated stress.
If you increase the amount of decimals for the schientific notation result you will probably be very close to 5.1754848e+007
In capture 3 you changed the load to 9000 and the result is 2.329e+007 = 23 290 000 N/m^2 so about 10 times below yield
So what is the problem?

Deajn Dejanovic Dec 8, 2015 2:00 AM (in response to Deajn Dejanovic)Crap, I have missed +007 or +008 of decimals. I was really confused what am I doing wrong. No problem any more, I get it now.
Thank very much for help!
