Abstract:

A method of determining the crack growth life of a thin, polymeric material is provided. The method includes the steps of providing a sample of the thin, polymeric material having a predetermined length, width and thickness. A groove is then formed in the sample followed by the formation of a crack in the groove. The sample is then secured in a test apparatus that cycles the sample in a bending mode at a predetermined frequency. The crack length is measured in the sample after a predetermined number of cycles. The crack growth data is collected over a period of cycles to determine the crack growth life in the sample.

Abstract:

An improved windshield wiper blade insert for mounting on a wiper blade carrier arm comprises a base portion, a shank portion and a wiping portion. The shank portion comprises an elastic response enhancing material. The material is preferably a metal that exhibits substantially total elastic recovery under the flexural stress and service conditions encountered by the wiper blade insert. In one embodiment, the shank portion contains a ribbon of spring metal with a thickness in the range of about 0. 001 to about 0. 004 inches. In a second embodiment, the elastic response member is an essentially rectangular solid formed from spring metal wire with a diameter in the range of about 0. 001 to about 0. 006 inches.
