Displacement field (mechanics) print that page

A displacement field is an assignment of displacement vectors for all points in a region or body that is displaced from one state to another. A displacement vector specifies the position of a point or a particle in reference to an origin or to a previous position. For example, a displacement

Continuum mechanics print that page

information about the particular material studied is added through a constitutive relation . Continuum mechanics deals with physical properties of solids and fluids which are independent of any particular coordinate system in which they are observed. These physical properties are then represented

Cantilever mechanics (orthodontics) print that page

Orthodontic_cantilever

Example of cantilever application in orthodontics A cantilever is used to obtain the buccal displacement of tooth 1.4 which is in cross bite. The cantilever may have many different configurations and uses in orthodontic therapy. The cantilevers may be utilized in all the planes of

Displacement operator print that page

Science

The displacement operator for one mode in quantum optics is the operator , where α is the amount of displacement in optical phase space , is the complex conjugate of that displacement , and and are the lowering and raising operators , respectively. The name of this operator is

Classical mechanics print that page

WilliamRowanHamilton.

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

Contact mechanics print that page

Kontakt_Spannungsoptik

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

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 ]

Fracture mechanics print that page

TankerSchenectady

In modern materials science , fracture mechanics is an important tool in improving the mechanical performance of materials and components. It applies the physics of stress and strain , in particular the theories of elasticity and plasticity , to the microscopic crystallographic defects

Deformation (mechanics) print that page

temperature changes within the body. Strain is a description of deformation in terms of relative displacement of particles in the body. Different equivalent choices may be made for the expression of a strain field depending on whether it is defined in the initial or in the final placement
