Maurice Leroy

Rheology, Physical and Mechanical Behavior of Materials 2 (eBook, ePUB)

Working at High Strain Rates, Forming, Sintering, Joining and Welding

• Format: ePub

Produktbeschreibung

This book studies the flow of materials and the influence of strain rates on the relationship between imposed stresses and the dynamic deformations obtained. It provides applications for shaping, molecular molding, shrink-fit assembly and welding, including details of the various specific processes for implementation at high strain rates, illustrated by numerous industrial examples.

Rheology, Physical and Mechanical Behavior of Materials 2 presents studies on the dynamic behavior of materials when subjected to mechanical, electromagnetic and electrohydraulic actions. The topics covered include dynamic structural memory, molecular molding, shaping, assembly and welding.

It is aimed at researchers involved in the mechanics of deformable media, as well as industrial design and manufacturing departments.
