The idea of this monograph is to present the latest results related to design and computation of engineering materials and structures. The contributions cover the classical fields of mechanical, civil and materials engineering up to biomechanics and advanced materials processing and optimization. The materials and structures covered can be categorized into modern steels and titanium alloys, composite materials, biological and natural materials, material hybrids and modern joining technologies. Analytical modelling, numerical simulation, the application of state-of-the-art design tools and sophisticated experimental techniques are applied to characterize the performance of materials and to design and optimize structures in different fields of engineering applications.Numerical Study in Biomodels of Maxillofacial Prosthesis.- Design model of damaged steel pipes for Oil and Gas Industry using Composite Materials.- The Use of Ultrasonic Waves and Analytical Modeling to Estimate Elasticity Modulus of Rubber Concrete Specimen.- The Effect of Dynamic Loading from Routine Activities on Mechanical Behavior of the Total Hip Arthoplasty.- Damage Detection in Materials Based on Computer Vision Wavelet Algorithm.- The Effect of the Bedding Length of Lintel in Masonry Walls on Their Load Bearing Capacity.- The Effect of Vertical Load on Seismic Response of Masonry Walls.- The Effect of Strain Hardening in Stainless Steels Submitted to Nitriding Treatment.- Mathematical Modeling of afterglow decay curves.- Comparative study for removal of the Methyl Red by two illites clays.- The Fretting Fatigue Behavior of the Bolted Assemblies.- Synthesis and Characterization of Nano Ti-50%Al by Mechanical Alloying.-.
