As a final step, recognizing that the integral over y is the definition of the beam's area moment
of inertia ‘I’,
Allows us to arrive at the Euler-Bernoulli beam equation,
Bearing Area: It is the product of the ‘pin diameter’ and the ‘specimen thickness’.
Bearing Load: It is the compressive load which acting on an interface.
Bearing Strength: It is the maximum bearing stress which not causes failure of the composite
(when applied through a cylindrical fastener surface).
Bearing Strain: It is the ratio of the deformation of the bearing hole (in the direction of the
applied force) to the pin diameter.
Bearing Stress: Applied load divided by bearing area (hole diameter times thickness).
Bearing Yield Strength: It is the bearing stress at which a material exhibits a specified limiting
deviation from the proportionality of bearing stress to bearing strain.
Bend Test: A test of ductility by bending or folding, usually with steadily applied forces. In
some instances the test may involve blows to a specimen having a cross section that is essentially
uniform over a length several times as great as the largest dimension of the cross section.
Bending Stiffness The sandwich panel stiffness deriving from the facing properties and distance
they are apart.
Benzoyl Peroxide (BPO): The catalyst used in conjunction with aniline accelerator or where
heat is used as an accelerator.
Bias Cut: Fabric cut at an angle (45o) to the warp & fill fibers.
Bias Fabric: A fabric in which warp and fill fibers are at an angle to the length.
Biaxial Load: It is a loading condition in which a laminate is stressed in two different directions
in its plane.
