Description
Stability of Nonlinear Shells: On the Example of Spherical Shells Volume 48Stability of NonLinear Shells is a compilation of the author's work on analyzing the behaviour of spherical caps and related shell structures under various (axisymmetric) load systems. Differing from other texts on shells of revolution, it is one of the first attempts to deal with effects of multi parameter load systems. This extension leads to the discovery of some new, hitherto unknown phenomena exhibited by these structures. In addition, the book
Stability of NonLinear Shells is a compilation of the author's work on analyzing the behaviour of spherical caps and related shell structures under various (axisymmetric) load systems. Differing from other texts on shells of revolution, it is one of the first attempts to deal with effects of multi-parameter load systems. This extension leads to the discovery of some new, hitherto unknown phenomena exhibited by these structures. In addition, the book presents a novel way to characterize properties of solutions of the governing equations for spherical caps - a classification anchored in a theory called reciprocal systems. The author has introduced a deformation map, a projection of multi-dimensional solutions to two-dimensional graphs, to enable analysts to gain insight into the physical meaning of the results obtained.Numerous examples illustrate the concepts introduced. This book also comes to grips with many misconceptions existing in engineering literature about the question of the stability of solutions.

Most comfortable pillows for my back
I have a really bad back along with sciatica so I use these pillows on my recliner chair, one for my back and one under my bottom. They make all the difference in the world. They are soft and squishy yet still offer support. They are a great value for sure. This blue color was about half the price of other colors with was fine with me because I put washable covers on them anyway. I frequently fall asleep on them. My dog loves when they accidentally fall on the floor because he curls up on them and falls asleep. He finds them very comfortable. I can't say enough good about these. They would be great on a bed or couch too or even as a floor cushion. They are high quality, well made pillows.

The trust we deposited in our selected shopping and companies.
Color: White, Size: 26x26 Inch
Excellent! Fix the covers and have a texturized and very fine fabrics made. Color as selected , size perfect any place deserved to be the best pillow and covers. Like the headboard for comfortable sitting position, also for sofas, chairing . Just try when buying and knowing the measurements and the (by experienced before) quality of the company manufactures and also like the best deliveries companies . Nothing else” excellent products” and thank You.

Glad I chose these Sturdy, Fluffy Pillows
Color: White, Size: 18x18 Inch
Took me forever to decide which pillows to buy....Price won out. There might be better out there, but I really can't see how. They plumped up really nicely. I once learned from a manager at a big box dept store when purchasing a goose down pillow how to 'activate' the pillow. Basically, he violently threw the pillow down onto the floor, then proceeded to beat the tar out of it....That's how it's done. I think many ppl don't do a good enough job when they get their pillows. I watched several videos from ppl who have purchased this type of pillow. And quite frankly, they do not know what they are doing....My pillows are very plump and awesome. I purchased the 20" squares and then chose 18" pillow covers to stuff them into. Perfection. Fat, soft, soothing pillows. Me and my Doggo are quite happy to lounge around on these durable puffs of fluffiness.
