the sphere of composite fabrics has obvious giant improvement long ago decade, New composite platforms are being regularly constructed for numerous functions. between such structures are steel, intermetallic, and superalloy matrix composites, carbon-carbon composites in addition to polymer matrix composites. whilst, a brand new self-discipline has emerged of energetic or clever fabrics, that are frequently developed as composite or heterogeneous media and buildings. One unifying subject in those assorted structures is the effect that uncoupled and paired eigenfields or transformation fields exert at the a number of sorts of total reaction, in addition to at the respective section responses. difficulties of this sort are presently thought of through diversified teams which can now not consistently savour the similarities of the issues concerned. the aim of the IUTAM Symposium on Transformation difficulties in Composite and lively fabrics held in Cairo, Egypt from March 10 to twelve, 1997 was once to compile representatives of the various teams in order that they may well engage and discover universal elements of those possible diversified troublesome areas. New instructions in micromechanics study in either composite and energetic fabrics have been additionally explored within the symposium. in particular, invited lectures within the components of inelastic habit of composite fabrics, form reminiscence results, functionally graded fabrics, transformation difficulties in composite buildings, and adaptive constructions have been brought and mentioned through the three-day assembly. This ebook comprises the broadcast contributions to the IUTAM Symposium.
