Interestingly, the longer the delay between initial injection and mold opening, the thicker the ratio of skins to foamed core and the higher the part's bending stiffness
and impact strength, although there is a slight loss in tensile properties (foam pores act like notches).
Moreover, matrix A, B and D represent in-plane stiffness matrix, in-plane coupling matrix and bending stiffness
The bending stiffness
of a curved panel is always higher than that of a flat panel.
The design quality of the laminated stator core determines its bending stiffness
and consequently affects the value of the radial vibration and reliability.
The global static bending stiffness
is defined as the ratio of the applied load to the maximum vertical defection at the side sill using Eq.
At a constant surface weight, the bending stiffness
in these structures could be increased by up to 600%.
Then they used this parameter as a criterion to choose the right type of a loop, which was used to evaluate the bending stiffness
of different fabrics.
The maximal thickness of typical hot-pressed plywood sheet is limited and, in many cases, there is insufficient bending stiffness
of these cables is virtually close to zero.
The relationship between certain mechanical properties (tension stiffness, residual extension, bending stiffness
, and shear stiffness) of fused composites and those of the outer fabric and fusible interlining were studied by Shishoo et al.
The collected lumber was tested to determine residual bending stiffness
Since then, the bending stiffness
has been used for Non-Destructive Evaluation (NDE) of strength of structural wooden members.
