Strain: |
(english) The intensity of deformation at a point in an object. See normal strain and shear strain. |
Strength: |
(english) A very general term that may be applied to a material or a structure. In a material, strength refers to a level of stress at which there is a significant change in the state of the material, e.g., yielding or rupture. In a structure, strength refers to a level of level of loading which produces a significant change in the state of the structure, e.g., inelastic deformations, buckling, or collapse. |
Stress resultant: |
(english) A system of forces which is statically equivalent to a stress distribution over an area. |
Structural model: |
(english) An idealization for analysis purposes of a real or conceived structure. A structural model includes boundaries limiting the scope of the analysis. Supports occur at these boundaries, representing things which hold the structure in place. |
Support: |
(english) A support contributes to keeping a structure in place by restraining one or more degrees of freedom. In a structural model, supports represent boundary entities which are not included in the model itself, e.g., foundations, abutments, or the earth itself. For each restrained translation degree of freedom at a support, there is a corresponding reaction force; for each restrained rotation degree of freedom, there is a reaction moment. |
Translation: |
(english) Motion of an object where the path of every point is a straight line. |
Transmissibility: |
(english) The principle stating that a force has the same external effect on an object regardless of where it acts along its line of action. |
Vector: |
(english) A mathematical entity having a magnitude and a direction in space. |
Velocity: |
(english) A vector quantity equal to the rate that position changes with time. |
Adsorption |
(Environmental Engineering) A surface phenomena in which a solute (soluble material) concentrates or collects at a surface (the adsorbent). |
