Constitutive Relations under Impact Loadings

Download or read book Constitutive Relations under Impact Loadings written by Tomasz Lodygowski and published by Springer Science & Business Media. This book was released on 2013-12-19 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes behavior of materials (ductile, brittle and composites) under impact loadings and high strain rates. The three aspects: experimental, theoretical and numerical are in the focus of interest. Hopkinson bars are mainly used as experimental devices to describe dynamic behavior of materials. The precise description of experimental techniques and interpretation of wave interaction are carefully discussed. Theoretical background refers to rate dependent thermo viscoplastic formulation. This includes the discussion of well posedness of initial boundary value problems and the solution of the system of governing equations using numerical methods. Explicit time integration is used in computations to solve dynamic problems. In addition, many applications in aeronautic and automotive industries are exposed.
