Biomechanical properties of bicortical and monocortical plate fixation for rib fractures in the adolescent human rib fracture model

Glowacki Jakub, Bartkowiak Tomasz, Paczos Piotr, Zielinski Michał, Smyczynski Mikołaj, Pelic Marcin

Acta of Bioengineering and Biomechanics

2023

Vol. 25, no. 3

The technical advancement of surgical stabilization of ribs often prevents the surgeons from fixation, despite the procedure`s documented improved outcomes. The aim of this study was to evaluate a less invasive approach involving a simplified monocortical rib fixation technique.

Experimental and numerical study of local stability of non-standard thin-walled channel beams

Grenda Michał, Paczos Piotr

Journal of Theoretical and Applied Mechanics

2019

Vol. 57 nr 3

549--562

The subject of the paper are cold-formed, thin-walled non-standard channel beams with stiffened webs. The local elastic buckling and limit load of the beams subjected topure bending are investigated. This study includes numerical, based on the Finite Element Method and the Finite Strip Method, calculations and actual tests of beams in the laboratory. The presented results give a deep insight into behaviour of such beams and may be used to validate analytical models.
