Beschreibung

This book studies metallic and composite materials and their mechanical properties in terms of stiffness and strength, illustrated through several case studies and exercises.

Rheology, Physical and Mechanical Behavior of Materials 4 focuses on the replacement of metal and wood products with fiber composites, which offer highly interesting directional mechanical properties. It studies various tests used to characterize the fiber-bonding pair in orthotropic layers and axes and also presents methods used to obtain stiffness and flexibility matrices, maximum stresses and deformations, and rupture envelopes. Finally, it presents various laminates, such as membrane and bending plates, tubular torsion, beat, buckling, twisting and sandwich structures.

This book is aimed at researchers involved in the mechanics of deformation, those studying or teaching this topic and industrial design and manufacturing departments.

Preface

In the case of relatively low loads, the deformation mechanisms for materials, parts and structures are reversible, and the elastic deformations are proportional to the stresses (Hooke’s law with E, Young’s modulus of elasticity).

In the case of complex loads, Hooke’s law is generalized into a three-dimensional relationship, and the linear nature of this law results in the following superposition principle: the stresses or deformations produced by the sum of several loading states on an elastic solid are equal to the sum of the stresses or deformations generated by each of the load states applied in isolation to the solid.

If the stress exceeds a certain value σe (or Re, σ0, Y), known as the elasticity limit stress, the phenomenon ceases to be reversible and linear, and the theory of elasticity can no longer be applied.

For three-dimensional loads, different sets of criteria for yield strength will define the corresponding domain in the stress space. These include the Tresca and Von Mises criteria, while Hill’s criteria are suitable for composites, and are often used in the calculations to determine the scale of parts and structures.

In many cases, it is sufficient to use the theory of elasticity, with the dimension criteria used to address safety concerns for the determination of the maximum permissible stress and/or maximum deformation.

NOTE.– The Tresca, Von Mises and Hill criteria are described in Leroy (2024), with special attention paid to the Hill criterion (Chapter 2, section 2.2) and its applications to composites.
