Plasticity induced crack closure in adhesively bonded joints under fatigue loading [PDF]
, 2015 The mean load of a cyclic loading has a large effect on fatigue crack growth rates in metallic materials and bonded joints. In metallic structures, this effect has been attributed to plasticity-induced crack closure, but little is known about the ...
