Re: [PSUBS-MAILIST] New Guy from down under needs help



Jon

Below is two quotes from the following link:

http://www.eurekamagazine.co.uk/article/21056/New-shape-helps-to-resist-pressure.aspx

-----
Along with principal lecturer Dr Andrew Little, Ross continues to optimise
both steel and carbon fibre tubular structures that can withstand very
high pressure by using corrugated constructions.
[...]
Using the Swedge concept with carbon fibre composite offers that increase
while reducing overall material content and Dr Little told us that: "These
tubes can withstand five to six times the pressure compared to a smooth
walled cylindrical tube made of the same material."
-----

Besides, I have collected some of the papers written by Carl T.F. Ross as
they have been available to me, ref

http://traktoria.org/files/personal_submarine/structural/

There you'll find the following papers (pdf-files] by Mr. Ross (et. al.):

1) Collaps of Corrugated Circular Cylinders under Uniform External Pressure.

2) Plastic General Instability of Ring-Stiffened Conical Shells under
External Pressure.

3) Vibration of large Ring-Stiffened Prolate Dome under External Water
Pressure.

Best regards,
Jens Laland
