Buckling behaviour of imperfect axially compressed cylinder with an axial crack
International Journal of Automotive and Mechanical Engineering, 2022 This paper studies the buckling behaviour of cylindrical shell structures with an axial crack subjected to axial compression. This work is both experimental and theoretical. The results of the test on four laboratory scale mild steel cylinders and the associated theoretical estimation of the buckling loads for a cylinder with no cracks are provided ...

Study on Axial Compression Stability of Q345 Large-Section Angle Steel Columns
Buildings, 2023 With the growing demand for the bearing capacity of columns, large-section angle steel (LAS) columns have been widely adopted. Q345 is the most commonly used steel, but research on the axial compression stability of LAS columns mainly focuses on steels ...

Case Studies in Construction Materials, 2023 A new type of stay-in-place formwork column (SFC) was proposed. The square prefabricated shell was made of basic magnesium sulfate cement based composite (BMSCC) and reinforced by angle steel frame. The SFC can be formed after ordinary concrete is poured.

On the role of localizations in buckling of axially compressed cylinders [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 The collapse of axially compressed cylinders by buckling instability is a classic problem in engineering mechanics. We revisit the problem by considering fully localized post-buckling states in the form of one or multiple dimples. Using nonlinear finite-element methods and numerical continuation algorithms, we trace the evolution of odd and even ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
