ROOT-MEAN-SQUARE STRESS [1 record]

Record 1 2014-04-07

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Strength of Materials
  • Physics of Solids
  • Plastic Materials
DEF

The square root of the mean value of the square of the stress over one cycle of deformation.

OBS

For a symmetrical sinusoidal stress, the root-mean-square stress equals the stress amplitude divided by [the square root of] 2.

OBS

The unit of measure of root-mean-square stress is the pascal (Pa).

OBS

root-mean-square stress: term and definition standardized by the International Organization for Standardization (ISO).

  • Physique des solides
  • Matières plastiques
DEF

Racine carrée de la valeur moyenne du carré de la contrainte sur un cycle de déformation.

OBS

Pour une contrainte sinusoïdale symétrique, elle est égale au quotient de l'amplitude de la contrainte par [la racine carrée de] 2.

OBS

L'unité de mesure de contrainte quadratique moyenne est le pascal (Pa).

OBS

DEF

Raíz cuadrada del valor promedio del cuadrado del esfuerzo sobre un ciclo de deformación.

OBS

Para un esfuerzo sinusoidal simétrico, el valor de la raíz cuadrada promedio del esfuerzo es igual a la amplitud del esfuerzo dividida por dos.
