Stability of cylindrical panel with variable thickness
Vietnam Journal of Mechanics, 2006 A linear buckling analysis based on the small deflection theory is presented for the cylindrical panel with sinusoidal changes in the shell thickness. The buckling load for simply supported cylindrical panel around the periphery is defined by using the ...

Stability of periodically supported slender structures and quantification of helix formation
Applications in Engineering Science, 2021 This paper investigates the configuration of periodically located cylindrical supports in order to impede buckling and/or failure of slender structures undergoing compression. This is done through parametric studies using a developed finite element model,

Experimental Investigation and Analysis of Dynamic Buckling of Drill String in Horizontal Well
Shock and Vibration, 2017 Buckling of tubulars has been the subject of many researches in the past. However, the models in previous research always followed the same assumptions: the friction and rotation effects are ignored.

Controlling lateral buckling of subsea pipeline with sinusoidal shape pre-deformation [PDF]
Ocean Engineering, 2018 Abstract It is common for subsea pipelines to operate at high pressures and high temperatures (HPHT) conditions. The build-up of axial force along the pipeline due to temperature and pressure differences from as-laid conditions coupled with the influence of the seabed soil that restricts free movement of the pipeline can result in the phenomenon ...

Buckling of the initial imperfect rectangular thin plate with variable thickness
Vietnam Journal of Mechanics, 2006 This paper analyzes the stability of the rectangular thin plate with sinusoidal changes in the plate thickness combined with initial curvature based on the large deflection theory. The buckling load for simply supported plates is defined using the energy

Shear Buckling Behavior of Tapered Steel Plate Girders with Sinusoidally Corrugated Webs
ce/papers, 2023 AbstractSteel plate girders with I‐section are frequently used in industrial buildings and bridge design as prismatic members that means as members with parallel flanges and rectangular webs. The structural efficiency can significantly be achieved if such members are designed with tapered webs that means with non‐rectangular webs.

Advanced Functional Materials, EarlyView.A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Advanced Materials, EarlyView.Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...
