THE USE OF OPTICALLY ACTIVE COATINGS IN THE SOLUTION OF PLANE ELASTO-PLASTIC PROBLEMS,

Abstract

The tests conducted permitted the development of a prescription and of a technology for the preparation of an optically active coating of epoxy resins of the EDP and EDL brand, with a maximum relative deformation of 6 - 7%. On the basis of a study of the relaxation properties of materials obtained from modified epoxy resins, optimum prescriptions are presented for research of deformation of the order of 10 - 12%. The possibility of the utilization of polyethyl carbamate as a photoelastic coating is shown. A composition of cold hardening glue was developed which provides a satisfactory adherence of the epoxy and the polyethyl carbamate coating to various materials. (Author)
