ABSTRACTThis internship wants to try building a model of numeric and choice theright parameter from the experimental data of anchor system in concrete in 2007at LGCIE INSA Lyon. It uses the finite element method in software CAST3Mwhich the elements are in 2D. There are two elements important, firstly concreteelement is taken from QUA4 and after for steel element is formed by elementBARR. The mesh is formed in 3 sizes for regarding the calculation convergence.Results are shown in force-displacement curve and stress-deformationdiagram. The maximum forces which appear are close to each other, that are251.25-258.62 kN and also the maximum displacement are 12mm. The concreteanchor is failed by shank fracture that is similar with the results of experimental."

"This book is very easy to read and one can gain a quick snapshot of computational issues arising in financial mathematics. SIAM review (46, 2004). The fourth edition is thoroughly revised and extended. Major revisions concern topics like calibration, Monte Carlo Methods, American options, exotic options and Algorithms for Bermuda Options. New figures, more exercises, more background material make this guide to the world of financial engineering a real must-to-have for everyone working in FE. "

"This textbook develops, analyzes, and applies numerical methods for evolutionary, or time-dependent, differential problems. Both PDEs and ODEs are discussed from a unified viewpoint. The author emphasizes finite difference and finite volume methods, specifically their principled derivation, stability, accuracy, efficient implementation, and practical performance in various fields of science and engineering. Smooth and nonsmooth solutions for hyperbolic PDEs, parabolic-type PDEs, and initial value ODEs are treated, and a practical introduction to geometric integration methods is included as well.The author bridges theory and practice by developing algorithms, concepts, and analysis from basic principles while discussing efficiency and performance issues and demonstrating methods through examples and case studies from numerous application areas."
