Centroid
Centroid or center of gravity is the point within an object from which the force
of gravity appears to act.
Centroid of 3D objects often (but not always) lies somewhere along the lines
of sym
Spherical Pressure Vessels
Pressure vessels are closed structures containing liquids or gases under
pressure. Examples include tanks, pipes, pressurized cabins, etc.
Shell structures : When pressure v
Torsion
Torsion is the twisting of a straight bar when it is loaded
by twisting moments or torques that tend to produce
rotation about the longitudinal axes of the bar.
For instance, when we turn a sc
Shear Forces and Bending Moments
Planar (2-D) Structures:
All loads act in the same plane and all deflections
occurs in the same plane (x-y plane)
Associated with the shear forces and bending
moments
3D Stress Components
The most general state of stress at a point may
be represented by 6 components
Normal Stresses
x
y
z
Shear Stresses
From equilibrium principles:
xy = yx , xz = zx , zy = yz
xy
y
Constitutive Equations (Linear Elasticity)
Equations that characterize the physical properties of the
material of a system are called constitutive equations. It is
possible to find the applied stresse
