Detailed stress analysis of a spherical acrylic submersible by 3-D finite element modeling

As the demand increases for ocean exploration to 3000 ft. (914.4 m) depth to collect samples,
to study the ocean surfaces, the problem of developing cracks at the interface of these manned acrylic submersibles following few hundred dives have become a common phenomenon. This has drawn considerable attention for reinvestigation of the spherical acrylic submersible in order to overcome this crack generation problem at the interface.
