Question

For non-dilatant materials, the maximum value of poisson's ratio is

Answer 1

Hii Dear,

◆ Answer -

For non-dilatant materials, the maximum value of Poisson's ratio is 0.5 .

● Poisson's ratio -

• Poisson's ratio is the negative of the ratio of transverse strain to axial strain.
• For shearing forces,

Poisson's ratio = transverse expansion / axial compression

ν = -εlat / εax

For example -

• metals ~ 0.33
• ceramics ~ 0.25
• polymers ~ 0.40
• non-dilatants < 0.50

Thanks dear...
