Professor Sluzalec is a well-known and respected authority in the
field of Computational Mechanics, and his personal experience forms
the basis of the book. Introduction to Nonlinear Thermomechanics
provides both an elementary and advanced exposition of nonlinear
thermomechanics. The scope includes theoretical aspects and their
rational application in thermal problems, thermo-elastoplasticity,
finite strain thermoplasticity and coupled thermoplasticity. The
use of numerical techniques for the solution of problems and
implementation of basic theory is included. Engineers, technicians,
researchers, and advanced students will find the book an extremely
useful compendium of solutions to problems. The scope is such that
it would also be an effective teaching aid.
The main purpose of this book is to provide a unified and
systematic continuum approach to engineers and applied physicists
working on models of deformable welding material. The key concept
is to consider the welding material as an thennodynamic system.
Significant achievements include thermodynamics, plasticity, fluid
flow and numerical methods. Having chosen point of view, this work
does not intend to reunite all the information on the welding
thermomechanics. The attention is focused on the deformation of
welding material and its coupling with thermal effects. Welding is
the process where the interrelation of temperature and deformation
appears throughout the influence of thermal field on material
properties and modification of the extent of plastic zones. Thermal
effects can be studied with coupled or uncoupled theories of
thermomechanical response. A majority of welding problems can be
satisfactorily studied within an uncoupled theory. In such an
approach the temperature enters the stress-strain relation through
the thennal dilatation and influences the material constants. The
heat conduction equation and the relations governing the stress
field are considered separately. In welding a material is either in
solid or in solid and liquid states. The flow of metal and
solidification phenomena make the welding process very complex. The
automobile, aircraft, nuclear and ship industries are experiencing
a rapidly-growing need for tools to handle welding problems. The
effective solutions of complex problems in welding became possible
in the last two decades, because of the vigorous development of
numerical methods for thermal and mechanical analysis.

The intention of this book is to reveal and discuss some aspects of
the metal fo- ing plasticity theory. The modern theory describes
deformation of metallic bodies in cold and hot regimes under
combined thermal and mechanical loadings. Th- mal and deformation
fields appear in metal forming in various forms. A thermal field
influences the material properties, modifies the extent of plastic
zones, etc. and the deformation of metallic body induces changes in
temperature distribution. The thermal effects in metal forming
plasticity can be studied at two levels, - pending on whether
uncoupled or coupled theories of thermo-plastic response have to be
applied. A majority of metal forming processes can be
satisfactorily studied within an uncoupled theory. In such an
approach the temperature enters the stress-strain relation through
the material constants and through the thermal dilatation. The
description of thermo-plastic deformation in metal forming is c-
ried out on the ground of thermodynamics.
