MMAN3400 - Objectives
Developing and furthering your skill in solving technical problems and
familiarizing you with analysis of membrane stresses, buckling

FLEXURAL (BENDING) STRESS IN
NON-HOMOGENEOUS BEAMS
Composite Beams:
Constructed of two or more different materials to develop more
efficient means for supporting loads.

SIMPLE BENDING
Objective:
To determine stresses and strains in thin straight beams
subject to bending loading ( Bernoulli Euler Beam Theory)
Thick beams - Timoshenko theory
Assumptions
The beam is long and thin:
(roughly
> 5).

The beam cross-section

UNSYMMETRIC BENDING
So far, we looked at simple bending
But in practice,
Unsymmetrical loading
There is a LPS but the load is not
applied on LPS.
There is no LPS.
Bending Moment not applied about a principal
axis (neutral axis):
Unsymmetrical section

Example 1
The spherical gas tank is fabricated by bolting together
two hemispherical thin shells of thickness 30 mm. If the gas
contained in the tank is under a gauge pressure of 2 MPa,
determine the normal stress developed in the wall of the tank
and in

Example 1
Example 2
Box beam with 4 boards nailed together. Each nail can support a shear force of 30 N.
Force on the beam = 80N. Maximum nail spacing , s =?
Shear flow is resisted at two surfaces and each nail can resist 30N

MOMENT OF INERTIA FOR AN AREA
2nd moment of an area
To calculate centroid of an area we used;
First moment of area =
For some topics in Mechanics of Solids we need second moment

SHEAR STRESSES AND SHEAR FLOWS IN BEAMS
(7.1 to7.5)
Objectives:
Determine shear stress in a prismatic beam
Determine the shear flow in a built-up beam
Determine the shear flow in thin-walled beam
Determine the shear center of a cross section
