what the strain gauge rosette measures is in status of plane strain or plane stress?

Submitted by Lin.Zhang on

I read some textbooks about mechanics of material. regarding strain measurement with strain gauge rosette, most of them regard it as  in the plain strain status.  But in my opinion, what the strain gauge rosette located is a fress surface. In this way, the thress stress components related to this plane, that is zz, zx, zy, should be zero, assuming that  the out normal of this plane is in the direction of Z axis.  then there are sigmaxx, sigma xy, sigmayy to be measured.  Is there anything wrong with my understanding?

Topic 36: Deep Sea Disposal of Oil and Gas Installations – Acceptable risk?

Submitted by Brenda Amanda on

The subject cannot be discussed
without reference to the Brent Spar incident in which Shell, with the UK
government permission, decided to sink the Brent Spar (a redundant oil storage
installation) into the North Sea as a decommission and disposal [1]. Greenpeace,
an Environment protection organization, rallied public support against the
move, culminating in Shell changing their stand even though they had earlier
met all conditions satisfying that the option was environmentally safe.
