A contribution named Experimental methodology for obtaining fatigue crack growth rate curves in mixed-mode I-II by means of variable cyclic displacement tests has been published by I. Jaeck et al. (amog them several AMADE members) in the International Journal of Fatigue. It presents a novel procedure to characterize the crack growth rate curve under fatigue mixed mode I + II loading in a MMB test by compliance monitoring and visual recording of the crack length. It is a time saving procedure especially when the explored severity range is wide.

Highlights
- A variable cyclic displacement test methodology applied to MMB is presented.
- The linear region of the crack growth rate curve is explored in one single test.
- The approach is applicable to any mode mixity.
- The crack length is monitored using a dynamic compliance calibration procedure.
- The testing effort, in terms of time and required material, is reduced.
