A detailed theoretical and
experimental analysis
of the rail shear test is presented. A
Fourier series
solution is obtained for the stresses in an idealized rail shear specimen. The theoretical results are quali tatively verified on fiber reinforced rubber composites. Rail shear data on the modulus and strength of current highmodulus rein forced composites is compared to predicted values obtained from lamination theory. Results show that, despite definite limitations, the rail shear test can be useful in the determination of the inplane shear properties of a laminated composite.

...A tensile test to investigate properties such as Young's moduli and Poison's ratio of fiberresin composites was suggested by ASTM test standard D303976; For evaluation of lamina inplane shear moduli, there are four generally accepted test methods [l]: the [f45], coupon test by Rosen [2], the offaxis coupon test, the rail shear test method [
3
], and the torsion test [4]...
