PROPORTIONAL LOADING TYPE 4

[ALEXANDROS STATHAS]

Hello can someone provide information with respect to the parameters l, tmin, tmax, p_0, dt that proportional loading type 4 requires, since the manual in the appendix A doesn't clarify them? I use Feap version 8.4.

[Prof. S. Govindjee]

Have a look in program/propld.f.  Search for "Type 4. Sawtooth proportional loading" (it is around line 380).
l = iexp(i)
p0 = ap(3,i)
dt = ap(4,i)

Thank you very much professor!

[Prof. R.L. Taylor]

There should also be a figure in the user manual that shows the two types of loading possible.   What is not clear?  It helps us to do updates to the manuals if you can explain what is hard to understand.

[Prof. S. Govindjee]

It is only mentioned on page 464 of the user manual but there is no figure or equation given.

Here is the figure.
