This monograph offers the elemental theorems of differential geometry in three-d house, together with a radical insurance of floor thought. via a chain of rigorously chosen and consultant mathematical versions this monograph additionally explains at size how those theorems are utilized in third-dimensional elasticity and in shell conception. The presentation is largely selfcontained, with a very good emphasis on pedagogy. particularly, no "a priori" wisdom of differential geometry or of elasticity conception is thought, the one specifications are an inexpensive wisdom of uncomplicated research, practical research, and a few acquaintance with usual and partial differential equations.
