From the reviews of the first edition: "This English translation of the French original ... is concerned with the control of accuracy in computation in linear and nonlinear mechanics. ... the calculations and concepts are clear and rigorous. Many original numerical illustrations are included. The book is intended for all those interested in mechanics: students, researchers, applied mathematicians and engineers concerned with the verification of models." (Carsten Carstensen, Mathematical Reviews, 2005k) "This English translation of the original 2001 French book discusses the evaluation of numerical error within the finite element context. ... The book is recommended to students, engineers and researchers contemplating the application of the finite element technique to constructing models and simulations of industrial problems." (J. C. F. Telles, Zentralblatt MATH, Vol. 1077, 2006)
