Alexandria Engineering Journal, 2018 In this paper, shapes of nonlinear blood vessels, surrounded by nonlinear soft tissues, and buckled due to radial pressure are solved for analytically and numerically. The blood flow rates through the bucked shapes are then computed numerically.

Strength determination for band-loaded thin cylinders [PDF]
, 2018 Cylindrical shells are often subjected to local inward loads normal to the shell that arise over restricted zones. A simple axisymmetric example is that of the ring-loaded cylinder, in which an inward line load around the circumference causes either ...

Dynamic buckling of an inextensible elastic ring: Linear and nonlinear analyses
, 2020 Slender elastic objects such as a column tend to buckle under loads. While static buckling is well understood as a bifurcation problem, the evolution of shapes during dynamic buckling is much harder to study.

Helical buckling of thin rods: FE modelling
MATEC Web of Conferences, 2018 In this paper, we utilize the Finite Element (FE) method to model twisting of long thin rods and capture the bifurcation scenarios leading to heli- cal buckling and various further post-buckling states.

Post-Buckling Behaviour of Steel Structures with Different Types of Imperfections
Applied Sciences, 2022 In this paper, the stability of steel members with a complex initial geometrical imperfection pattern are analysed. This issue is extremely important in the case of slender structures, characterised by multiple close critical loads and modal interactions,
