and additionally considers discontinuity in longitudinal displacement due to presence of the crack. Therefore, this multi-spring model can consider coupled effects between the axial force and bending moment at the cracked section. The generalized differential...

In this paper, a multi-spring model is used for modelling of the crack in a micro/nanobeam

under axial compressive load based on a modified couple stress theory. This model inc-

ludes an equivalent rotational spring to transmit...
