Welcome on piarc.org!

PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

Term of the Road Dictionary

modulus of elasticity

  • Language : PIARC Road Dictionary / English
  • Theme : Scientific and Technical Tools Physics and Chemistry
  • Definition : Value representing the deformability of an homogeneous orthotropic elastic body. Note: given a prismatic elastic body with length L and cross-sectional area S, which has a deformation ΔL when submitted to a normal force N on surface S. The modulus of elasticity is: E = N/S x L/ΔL (unit: Pa).
  • Synonyms : elastic modulus / Young's modulus

Elastizitätsmodul 2

  • Language : PIARC Road Dictionary / German
  • Theme : Wissenschaftliche und technische Arbeitsmittel Physik und Chemie
  • Definition : Wert, der die Verformbarkeit eines homogenen, orthotropen, elastischen Körpers beschreibt. Annahme: Ein prismatischer elastischer Körper mit der Länge L und einer Querschnittsfläche S erfährt eine Verformung ΔL, wenn eine Normalkraft N auf die Fläche S aufgebracht wird. Der Elastizitätsmodul ergibt sich dann zu: E = N/S x L/ΔL (Einheit Pa).
  • Synonyms : E-modul
