Distortional buckling of simple lipped channel in bending results of the experimental analysis versus direct strength methods
(2006-12-01)
Cold-formed steel members are subject to failure caused by buckling, normally under loads smaller than those corresponding to partial or total yielding of the cross section. The buckling of members in bending can be ...
Numerical assessment of temperature effects on concrete failure behavior
(Springer, 2018-08)
This work focuses on the evaluation of temperature effects on concrete failure behavior and modes by means of a realistic thermodynamically consistent non-local poroplastic constitutive model, previously developed by the ...
