Buckling and postbuckling of size-dependent cracked microbeams based on a modified couple stress theory
M. Akbarzadeh Khorshidi, M. Shariati Ferdowsi University of Mashhad, Mashhad, Iran
Abstract:
The elastic buckling analysis and the static postbuckling response of the Euler–Bernoulli microbeams containing an open edge crack are studied based on a modified couple stress theory. The cracked section is modeled by a massless elastic rotational spring. This model contains a material length scale parameter and can capture the size effect. The von Karman nonlinearity is applied to display the postbuckling behavior. Analytical solutions of a critical buckling load and the postbuckling response are presented for simply supported cracked microbeams. This parametric study indicates the effects of the crack location, crack severity, and length scale parameter on the buckling and postbuckling behaviors of cracked microbeams.
