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 strain over one cycle of deformation.

OBS

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

OBS

Its value is dimensionless.

OBS

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

DEF

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

OBS

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

OBS

Sa valeur est sans dimension.

OBS

déformation quadratique moyenne : terme et définition normalisés par l'Organisation internationale de normalisation (ISO).

DEF

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

OBS

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