Materials Mechanics

This book deals with both mathematical modeling and experimental studies related to systems relevant for various civil engineering fields. The book explores the intriguing effects of phenomena occurring at lower length scales on the behavior at higher scales, as the influence of polypropylene macro-fiber thickness in fiber-reinforced concrete mechanical strengths. Generally speaking, the book addresses several key topics, including artificial intelligence applied to the control and monitoring of construction site personnel, finite element models for endplate beam-to-column connections under various load conditions, random functionally graded micropolar beams, and many others. The book explores the design and study of microstructures aimed at increasing the toughness and durability of novel materials in building and construction, based also on the re-utilization of residues and wastes of metallurgical industry produces. In conclusion, the book highlights innovative approaches to various fields of civil engineering, including microstructures for enhanced mechanical properties, offering insights into design strategies.

This book is a pilot course in the Mechanics of Materials (Elasticity and Strength) offered to engineering students throughout the bachelor study. The main objective of this course is for students of engineering to develop the ability to analyse a given problem in a simple and logical manner and to its solution, apply a few fundamental and well-understood principles. This book consists of 6 chapters which include fundamental types of loading: axial, torsional, bending, and transversal. Each chapter contains many solved and unsolved problems.

This volume records the proceedings of an international symposium on "ME­ CHANICS OF SHEET METAL FORMING: Material Behavior and Deformation Analysis." It was sponsored and held at the General Motors Research Labora­ tories on October 17-18, 1977. This symposium was the twenty-first in an annual series. The objective of this symposium was to discuss the research frontiers in experimental and theoretical methods of sheet metal forming analysis and, also, to determine directions of future research to advance technology that would be useful in metal stamping plants. Metal deformation analyses which provide guide­ lines for metal flanging are already in use. Moreover, recent advances in computer techniques for solving plastic flow equations and in measurements of material parameters are leading to dynamic models of many stamping operations. These models would accurately predict the stresses and strains in the sheet as a function of punch travel. They would provide the engineer with the knowledge he needs to improve die designs. The symposium papers were organized into five sessions: the state of the art, constitutive relations of sheet metal, role of friction, sheet metal formability, and deformation analysis of stamping operations. We believe this volume not only summarizes the various viewpoints at the time of the symposium, but also pro­ vides an outlook for materials and mechanics research in the future.
