Continuum mechanics print that page

Modelling an object as a continuum assumes that the substance of the object completely fills the space it occupies. Modelling objects in this way ignores the fact that matter is made of atoms , and so is not continuous; however, on length scales much greater than that of inter-atomic distances | 2011/10/1 6:28:32

Shakedown (continuum mechanics) print that page

In continuum mechanics , elastic shakedown behavior is one in which plastic deformation takes place during running in , while due to residual stresses or strain hardening the steady state is perfectly elastic. Plastic shakedown behavior is one in which the steady state is a closed elastic | 2010/9/26 11:15:02

Tensor derivative (continuum mechanics) print that page

The derivatives of scalars , vectors , and second-order tensors with respect to second-order tensors are of considerable use in continuum mechanics . These derivatives are used in the theories of nonlinear elasticity and plasticity , particularly in the design of algorithms for numerical | 2011/5/7 3:27:30

Fluid mechanics print that page


The study of fluid mechanics goes back at least to the days of ancient Greece , when Archimedes investigated fluid statics and buoyancy and formulated his famous law known now as the Archimedes' Principle . Rapid advancement in fluid mechanics began with Leonardo da Vinci (observation

Solid mechanics print that page

As shown in the following table, solid mechanics inhabits a central place within continuum mechanics . The field of rheology presents an overlap between solid and fluid mechanics . Continuum mechanics The study of the physics of continuous materials Solid mechanics The study of | 2010/10/2 1:36:58

Classical mechanics print that page


In physics , classical mechanics is one of the two major sub-fields of mechanics , which is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces. The study of the motion of bodies is an ancient one, making classical mechanics one

Lagrangian mechanics print that page

In Lagrangian mechanics , the trajectory of a system of particles is derived by solving the Lagrange equations in one of two forms, either the Lagrange equations of the first kind , [ 1 ] which treat constraints explicitly as extra equations, often using Lagrange multipliers ; [ 2 ] [ 3 ] | 2011/5/10 11:29:09

Stress (mechanics) print that page

In continuum mechanics , stress is a measure of the internal forces acting within a deformable body . Quantitatively, it is a measure of the average force per unit area of a surface within the body on which internal forces act. These internal forces are a reaction to external forces applied | 2011/5/18 18:35:03

Statistical mechanics print that page

Statistical mechanics provides a molecular-level interpretation of macroscopic thermodynamic quantities such as work , heat , free energy , and entropy . It enables the thermodynamic properties of bulk materials to be related to the spectroscopic data of individual molecules. This ability | 2011/5/27 2:52:13

Contact mechanics print that page


Contact mechanics is foundational to the field of mechanical engineering ; it provides necessary information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness . Principles of contacts mechanics can be applied in areas such
