Nov 26, 2009 · The program states that nuab must be less than sqrt (Eb/Ea). For the material in question this sets an upper limit on nuab of 0.25, whereas the manufacturers data gives a value of 0.4. As a further aside Nafems benchmark example 1 has E1=1e5 E2=5e3, and nu12=0.4, however sqrt (5e3/1e5)=0.22. "nuab must be less than sqrt (Eb/Ea)" this does not ...
