linear contraction
[ˈlɪniər kənˈtrækʃən]
nounpl: linear contractions
contração linear
1. A reduction in length of a material along one dimension due to cooling, stress, or other physical changes, expressed as a proportion of the original length
The linear contraction of the metal rod was measured at 0.5% when cooled to -50°C.
A contração linear da barra de metal foi medida em 0,5% quando resfriada a -50°C.
2. In mathematics and physics, a transformation that uniformly reduces distances in one direction while preserving distances in other directions
The linear contraction coefficient is essential for calculating thermal stress in construction materials.
O coeficiente de contração linear é essencial para calcular a tensão térmica em materiais de construção.
Linear contraction is a critical concept in Brazilian engineering and construction industries, particularly in civil engineering projects where materials like concrete, steel, and wood undergo thermal changes. The term is universally understood in technical and academic contexts across both Brazil and Portugal. In industrial applications, proper calculation of linear contraction coefficients is essential for structural integrity and is regulated by engineering standards (ABNT in Brazil).
