The papers presented at the conference provide evidence that computer-based models, and in particular numerical methods, are being increasingly used for the solution of the many problems associated with biomedical engineering. The range of subject areas presented include modeling of hip and knee joint replacements, non-linear analysis of hard and soft tissue, methods for the simulation of bone adaptation, bone reconstruction using implants, and computational techniques to model human impact. Also included are papers investigating the application of numerical techniques to orthodontic treatment and dental mechanics, and new methods for assessment of fatigue damage in cemented hip prostheses. This book is comprised of the proceedings of the second international symposium on Computer Methods in Biomechanics and Biomedical Engineering, held at Swansea, Wales, UK, 21-24 September 1994. The symposium concentrated on the rapid progress and advances being made in computer modelling applied to the
