Abstract:
Activity on the subject program for the first year is described, including a survey of literature, equipment, research efforts, and nondestructive testing needs. As a result of this survey, the second portion of the first year's activity was directed toward the development of thin sheet nondestructive test instrumentation in the field of high frequency eddy current equipment, Lamb wave ultrasonic techniques, and electrostatic testing techniques. The eddy current instrument operates at 5 Mc. with future work being planned for frequencies to 50 Mc. The Lamb wave techniques are directed toward finding material parameter variations and laminations in thin sheet. The electrostatic tests utilized thin nonconductive samples with application to ceramic coated refractories considered.
