ABSTRACT:; y( q& x0 I4 a
Blade designers are in need of accurate strength and stiffness data for the materials used in their design. In some parts of the blade, loading is dominated by shear. For accurate modeling of the design, an appropriate description of the shear characteristics of the material is required, including the non-linearity in shear/strain responses. The objective of this paper is to compare different methods of obtaining shear characteristics of fiber reinforced plastics. The differences in measured shear modulus are significantly smaller than the differences in observed maximum shear strengths. |
