Dynamic behavior of suture-anastomosed arteries and implications to vascular surgery operations

Roussis, P. C.; Giannakopoulos, A. E.; Charalambous, H. P.; Demetriou, D. C.; Georghiou, G. P. (2015)

Background: Routine vascular surgery operations involve stitching of disconnected human arteries with themselves or with artificial grafts (arterial anastomosis). This study aims to extend current knowledge and provide ...

Nonlinear dynamic analysis of multi-base seismically isolated structures with uplift potential I: formulation

Tsopelas, P. C.; Roussis, P. C.; Constantinou, M. C. (2009)

The complexity of modern seismically isolated structures requires the analysis of the structural system and the isolation system in its entirety and the ability to capture potential discontinuous phenomena such as isolator ...

Nonlinear dynamic analysis of multi-base seismically isolated structures with uplift potential II: verification examples

Roussis, P. C.; Tsopelas, P. C.; Constantinou, M. C. (2010)

The work presented in this paper serves as numerical verification of the analytical model developed in the companion paper for nonlinear dynamic analysis of multi-base seismically isolated structures. To this end, two ...

Study on the dynamic behavior of arterial end-to-end anastomosis

Roussis, P. C.; Giannakopoulos, A. E.; Charalambous, H. P. (2014)

Vascular disorders, such as atherosclerosis and aneurysms are treated by vascular surgery operations, and involve the stitching of disconnected human arteries with themselves or with artificial grafts. Stitching techniques ...

Suture Line Response of End-to-Side Anastomosis: A Stress Concentration Methodology

Roussis, P. C.; Giannakopoulos, A. E.; Charalambous, H. P. (2015)

End-to-side vascular anastomosis has a considerable complexity regarding the suturing of the juncture line between the artery and the graft. The present study proposes a stress–concentration methodology for the prediction ...

Three-dimensional nonlinear dynamic analysis of multi-base seismically isolated structures with uplift potential

Roussis, P. C.; Tsopelas, P. C.; Constantinou, M. C. (2010)

The complexity of modern seismically isolated structures requires tools for fast, accurate and reliable analysis and the ability to capture potential discontinuous phenomena such as isolator uplift and their effects on the ...
