6. Angular Momentum Balance
The chapter delves into the balance of angular momentum, detailing the contributions of traction and body forces. It explores the dynamics of deriving the angular momentum balance equation and its representation in a coordinate system, culminating in a symmetric stress tensor outcome. Furthermore, it discusses the relationship between externally applied loads and the stress matrix within a fluid body at rest, integrating fundamental principles of mechanics and fluid dynamics.
Sections
This section discusses the balance of angular momentum in a cuboidal mass, detailing contributions from traction and body forces, dynamics terms, and simplifying assumptions in derivation.
This section discusses how externally applied distributed loads on a body relate to the stress tensor, with focus on deriving the relationships for stress equilibrium.
This section explains the concepts of traction and stress in a static fluid, emphasizing how pressure relates to these forces.
Angular momentum balance can be derived considering both traction and body force contributions.
The stress matrix must remain symmetric, even under the influence of external forces or acceleration.
The pressure within a fluid body at rest generates traction that aligns with the normal to the surfaces of the fluid.
Angular Momentum Balance
A principle in mechanics that equates the sum of angular momentum contributions from various forces, including traction forces and body forces.
Stress Matrix
A mathematical representation of stress states within a material, capturing internal forces acting on a differential volume element.
Traction
Force per unit area acting on a material surface, essential for understanding how external loads affect internal stress states.
Fluid Statics
The study of fluids at rest, emphasizing the role of pressure and its effects on forces within fluids.
