Curved Beams
Curved Beam
Due to curvature of the beam, normal strain does not vary
linearly with depth as in the case of a straight beam.
Therefore NA will not pass through the centroid. T

Unsymmetrical Bending
Bending in two planes (xy and xz.)
Neutral axis does not coincide with the principal axes of cross-section
If the cross-section has an axis of symmetry, this axis mu

Failure Theories
For ductile materials, failure is specified by initiation
of yielding
For brittle materials, failure is specified by fracture
For ductile materials, the popular yield the

State of Stress: 3D
If we know the stresses on any 3 mutually perpendicular planes through a point, then we can
determine the stresses on any inclined plane
through the same point

Mohrs Circle
Mohrs circle is a graphical method for solving
stresses, strains, moments of inertia, on
arbitrary planes.
It is an alternate method to the
