Deformation (mechanics) print that page

The cause of a deformation is not pertinent to the definition of the term. However, it is usually assumed that a deformation is caused by external loads, [ 2 ] body forces (such as gravity or electromagnetic forces), or temperature changes within the body. Strain is a description of deformation

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

Discontinuous Deformation Analysis print that page


DDA method Various modifications to the original DDA formulation have been reported in the rock mechanics literature. In the original DDA formulation a first order polynomial displacement function was assumed, so the stresses and strains within a block in the model were constant. This approximation

Applied mechanics print that page

Applied mechanics , as its name suggests, bridges the gap between physical theory and its application to technology . As such, applied mechanics is used in many fields of engineering , especially mechanical engineering . In this context, it is commonly referred to as engineering mechanics

Fracture mechanics print that page


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

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

Soil mechanics print that page


concludes with some examples of geotechnical engineering applications of the principles of soil mechanics such as slope stability, lateral earth pressure on retaining walls, and bearing capacity of foundations. Slope instability issues for a temporary flood control levee in North Dakota

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

Frictional contact mechanics print that page

Frictional contact mechanics is concerned with a large range of different scales. At the macroscopic scale, it is applied for the investigation of the motion of contacting bodies (see Contact dynamics ). For instance the bouncing of a rubber ball on a surface depends on the frictional interaction
