Theory of elasticity is a branch of mechanics that deals with the deformation and stress of solid bodies under external forces. It is one of the fundamental topics in engineering, physics, and mathematics, as it helps us understand how materials behave under various loading conditions. Theory of elasticity also has many practical applications in fields such as structural engineering, aerospace engineering, biomechanics, geophysics, nanotechnology, and more.

In this article, we will introduce you to one of the most comprehensive and authoritative books on theory of elasticity: Theory of Elasticity by Stephen P. Timoshenko and James N. Goodier. This book was first published in 1934 by Timoshenko, who is widely regarded as the father of modern engineering mechanics. He was later joined by Goodier, who was his former student and colleague at Stanford University. Together, they revised and updated the book several times, incorporating the latest developments and research in the field.


We will also show you how to download the solution manual for this book for free. The solution manual contains detailed answers and explanations for all the problems and exercises in the book. It is a valuable resource for students, instructors, researchers, and practitioners who want to master theory of elasticity and apply it to real-world problems.


Theory of elasticity basics




Theory of elasticity is based on some fundamental concepts and principles that we will briefly review in this section.


Definition and assumptions of linear elasticity




A solid body is said to be elastic if it returns to its original shape and size after the removal of external forces. Linear elasticity is a simplified model that assumes that the deformation of the body is small compared to its dimensions, and that the stress-strain relationship is linear and isotropic. Isotropic means that the material properties are independent of direction.


Stress, strain, and constitutive relations




Stress is a measure of the internal force per unit area acting on a cross-section of a body. It can be represented by a second-order tensor with nine components in three dimensions. Strain is a measure of the relative change in length or angle of a line element in a body due to deformation. It can also be represented by a second-order tensor with nine components in three dimensions.


The constitutive relations are equations that relate stress and strain for a given material. For linear elastic isotropic materials, the most common constitutive relations are Hooke's law for normal stress-strain (also known as Young's modulus) and Poisson's ratio for transverse strain. Hooke's law states that the normal stress is proportional to the normal strain, while Poisson's ratio is the ratio of the transverse strain to the normal strain.


Equilibrium and compatibility equations




The equilibrium equations are derived from the principle of conservation of linear momentum, which states that the sum of the external and internal forces acting on a body must be zero. In differential form, the equilibrium equations can be written as a system of three partial differential equations in terms of the stress components.


The compatibility equations are derived from the requirement that the strain components must be consistent with the displacement field of the body. In differential form, the compatibility equations can be written as a system of six partial differential equations in terms of the strain components.


Boundary and initial conditions




The boundary conditions specify the values or relations of the displacement or stress components on the boundary of the body. There are two types of boundary conditions: essential (or Dirichlet) and natural (or Neumann). Essential boundary conditions prescribe the displacement components, while natural boundary conditions prescribe the stress components.


The initial conditions specify the values or relations of the displacement or velocity components at the initial time. They are usually given for dynamic problems involving time-dependent loading or inertia effects.


Plane stress and plane strain problems




Plane stress and plane strain are two special cases of theory of elasticity that simplify the analysis of two-dimensional problems. Plane stress occurs when the body is thin and the stress components normal to the plane are negligible. Plane strain occurs when the body is long and the strain components normal to the plane are negligible. In both cases, the problem reduces to four unknowns (two displacement components and two stress components) instead of nine.


Theory of elasticity applications




Theory of elasticity has many applications in engineering and science, as it can model various phenomena and problems involving elastic deformation and stress. In this section, we will present some examples of theory of elasticity applications.


Torsion of prismatic bars




Torsion is the twisting of a bar due to a torque applied at its ends. The torsion problem can be solved by using theory of elasticity, assuming that the bar has a constant cross-section (prismatic) and that it is subjected to pure torsion (no bending or axial force). The solution gives the distribution of shear stress, shear strain, and angle of twist along the bar, as well as the relation between torque and angle of twist.


Bending of beams




Bending is the deformation of a beam due to a transverse load applied perpendicular to its axis. The bending problem can be solved by using theory of elasticity, assuming that the beam has a constant cross-section (prismatic) and that it is subjected to pure bending (no shear or axial force). The solution gives the distribution of normal stress, normal strain, and curvature along the beam, as well as the relation between bending moment and curvature.


Buckling of columns




Buckling is the instability of a column due to a compressive load applied along its axis. The buckling problem can be solved by using theory of elasticity, assuming that the column has a constant cross-section (prismatic) and that it is subjected to pure compression (no bending or shear). The solution gives the critical load at which buckling occurs, as well as the mode shape and frequency of buckling.


Stress concentration and fracture mechanics




Stress concentration is the phenomenon where stress is higher than average near a discontinuity or irregularity in a body, such as a hole, notch, crack, or fillet. Stress concentration can lead to failure or fracture of the body if it exceeds its strength or toughness. Fracture mechanics is a branch of theory of elasticity that studies how cracks propagate and interact with stress fields. Fracture mechanics can predict the critical stress intensity factor or fracture toughness at which fracture occurs, as well as the crack growth rate and direction.


Thermal stresses




Thermal stresses are stresses induced by temperature changes in a body. Thermal stresses can arise from external heat sources or sinks, internal heat generation or dissipation, or thermal expansion or contraction. Thermal stresses can be analyzed by using theory of elasticity, assuming that the body has a linear thermal expansion coefficient and that it is subjected to small temperature changes. The solution gives the distribution of thermal stress and strain in terms of temperature gradients and boundary conditions.


Theory of elasticity advanced topics




Theory of elasticity can also deal with more complex and realistic situations that involve nonlinearities, anisotropies, composites, plates, shells, waves, vibrations, and 71b2f0854b
