Description
Book SynopsisThere are three fundamental issues associated with the mechanical behavior of engineering materials and structures: their stiffness, strength, and life. This book provides a conceptual and operational framework that treats these issues from the standpoint of technical difficulty.
Trade Review"...the authors should be congratulated for producing a well-organised, well-written, useful book that nay materials and structures engineer and basic and applied science researchers should know, own and use in their professional activities..." (

"...a useful reference..." (AIAA Journal, Vol. 40, No. 10, October 2002)
