Strain-stiffening seal

Soft Matter, 2022
A strain-stiffening seal is soft to accommodate installation but stiff to block fluid flow. Leak by elastic deformation or rupture? We construct diagrams in which the two modes of leak are demarcated.

Stiffener Effectiveness Approach for Optimal Stiffener Placement on Curvilinear Stiffened Panel

50th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2009
Stiffened panels with curved stiffeners have shown a potential for structural tailoring of metallic panels. However, the optimal placement of the stiffener curves has remained a challenge, both due to the presence of multiple local minima in the design space, as well as the associated CPU cost to solve the problem. This paper presents a new approach to

Buckling of stiffened plates and design of stiffeners

International Journal of Pressure Vessels and Piping, 1997
Abstract This paper presents a closed-form solution of critical instability stresses for simply supported rectangular plates with an arbitrary number of stiffeners in longitudinal and/or transverse directions. It is shown that there are only two buckling modes that are coupled to each other for single direction stiffened plates and four for double ...

Effect of Stiffeners on the Natural Frequencies of Stiffened Plate

2021
The present study deals with the effectiveness of stiffeners on the dynamic response of the plate structure. Two boundary conditions, clamped and simply supported on all edges, are considered. A finite element-based software, ANSYS Workbench 14.0, is used to model and analyse the stiffened plates. Flat stiffeners are used in the study, and some results

Free Vibration of Stiffened Plate with Cracked Stiffeners

Advances in Applied Mathematics and Mechanics
Summary: In this paper, a new cracked stiffener model for the stiffener with a part-through and open crack is proposed, considering the compatibility condition of displacements between the plate and the stiffener. Based on the first-order shear deformation theory, the free vibration of stiffened isotropic plates with cracked stiffeners are investigated
