Commerce the loss of merchandise in a retail store through theft or damage

Shrinkage

A decrease in dimensions occurring when a material experiences temperature changes.

Shrinkage

 

reduction in the linear dimensions and volume of materials caused by loss of moisture, contraction, hardening, and other processes. The shrinkage of ceramics and concrete is of considerable importance. Molded clay products are subject to shrinkage during drying and firing. The shrinkage of concrete occurs during air hardening and is due to the evaporation of water from the capillaries in cement rock. The shrinkage of metals and metal alloys during crystallization is due to the reduction in volume on transition from the liquid state to the solid, the additional reduction in volume on cooling from the solidification point to room temperature, and the penetration of molten metal into the inner part of the congealing mass and all the cavities and cracks formed during molding of the ingot or shaped casting.

Reduction over time in the vertical dimensions of structural components, such as stone and wood walls and heat-insulating fill, is often called settling.

shrinkage

(engineering)
Contraction of a molded material, such as metal or resin, upon cooling.
Contraction of a plastics casting upon polymerizing.
(geology)
The decrease in volume of soil, sediment, fill, or excavated earth due to the reduction of voids by mechanical compaction, superimposed loads, natural consolidation, or drying.

shrinkage

1. The reduction in dimensions of a piece of wood during drying; reduction is very slight along the grain, but a reduction of 5 to 6% in width is common for dry flat-sawn boards.
2. The volume decrease of concrete caused by drying and chemical changes.
3. The proportionate decrease in dimensions or volume of a material, usually as a result of a change in temperature.
