A method and apparatus for subjecting thin sheets, webs, foils, films and the like to in-plane shear stresses. A rectangularly shaped specimen is grasped at its long sides, opposing forces acting in the direction of the long sides are applied to the long sides and portions the sheet between the long sides are placed between stabilizing bars that maintain the web in its planar shape and prevent buckling of the web under the forces before its ultimate shear strength is reached.
