SHEAR MODULUS DETERMINATION IN LAMINATED COMPOSITE MATERIALS.

Pagination or Media Count:
The report discusses limitations on two widely used methods of measuring shear modulus of fiber reinforced composites. In particular, it is shown that for certain types of fiber lay-ups neither a plate twisting test nor a torsion tube can be used to measure shear modulus directly. Classical theory of laminated plates and cylindrical shells of the Donnell type provides the basis for these conclusions. Circumstances under which these tests can be used to measure shear modulus directly are also discussed. Author
