Two beams, one of material A and one of material B are loaded in flexure such that neither
material exceeds its yield strength. The beams have the same cross-sectional dimensions. The
stress-strain behaviors of the materials are shown below. Which material will deflect the most if
both are subjected to the same load? Briefly explain why.
Solution
It is given that Loading and cross section area is same.
From the stress strain curve of the materials A and B,it can be observed that, Youngs modulus
'E' is more for material 'A'. As the Deflection is indirectly proportional to 'E', material 'B'
will under go more deflection compared to 'A.
