What is the ratio between the maximum elastic moment, MY, and the maximum plastic moment, MP, for a solid rectangular section made from a ductile, elastoplastic material? What is this ratio referred to?

Respuesta :

Answer:

Shape factor

Explanation:

Shape factor is the ratio of maximum plastic moment to maximum elastic moment.Shape factor is denoted by K.

Shape factor can be given as

[tex]K=\dfrac{M_p}{M_y}[/tex]

[tex]K=\dfrac{\sigma _yZ_p}{\sigma _y Z}[/tex]

[tex]K=\dfrac{Z_p}{ Z}[/tex]

For a solid rectangular section made from ductile material shape factor is 1.5 .
