2. Section modulus - Wikipedia

   en.wikipedia.org/wiki/Section_modulus

   The plastic section modulus is used to calculate a cross-section's capacity to resist bending after yielding has occurred across the entire section. It is used for determining the plastic, or full moment, strength and is larger than the elastic section modulus, reflecting the section's strength beyond the elastic range. [1] Equations for the ...

3. Deformation (engineering) - Wikipedia

   en.wikipedia.org/wiki/Deformation_(engineering)

   An object in the plastic deformation range, however, will first have undergone elastic deformation, which is undone simply be removing the applied force, so the object will return part way to its original shape. Soft thermoplastics have a rather large plastic deformation range as do ductile metals such as copper, silver, and gold.

   Traditional Romanian tablecloth made in Maramureș Cover for Square Table, Qing dynasty, Qianlong period, 1736–1795, China. Cut and voided silk velvet. Detail of crochet tablecloth. A tablecloth is a cloth used to cover a table. Some are mainly ornamental coverings, which may also help protect the table from scratches and stains.

5. Four-point flexural test - Wikipedia

   en.wikipedia.org/wiki/Four-point_flexural_test

   The four-point flexural test provides values for the modulus of elasticity in bending, flexural stress, flexural strain and the flexural stress-strain response of the material.

6. Roark's Formulas for Stress and Strain - Wikipedia

   en.wikipedia.org/wiki/Roark's_Formulas_for_Stress...

   The book covers various subjects, including bearing and shear stress, experimental stress analysis, stress concentrations, material behavior, and stress and strain measurement. It also features expanded tables and cases, improved notations and figures within the tables, consistent table and equation numbering, and verification of correction ...

7. Poisson's ratio - Wikipedia

   en.wikipedia.org/wiki/Poisson's_ratio

   Poisson's ratio of a material defines the ratio of transverse strain (x direction) to the axial strain (y direction)In materials science and solid mechanics, Poisson's ratio (symbol: ν ()) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.
