RADC-TR-89-281, IN-HOUSE REPORT: RELIABILITY ASSESSMENT USING FINITE ELEMENT TECHNIQUES (NOV-1989)

RADC-TR-89-281, IN-HOUSE REPORT: RELIABILITY ASSESSMENT USING FINITE ELEMENT TECHNIQUES (NOV-1989)., Finite element analysis (FEA) is a computer simulation technique that is used to predict the thermal and mechanical response of a structure. Rome Air Development Center (RADC) has used FEA to predict the response in various electronic assemblies. This particular study was concerned with the reliability of surface mounted microwire boards. A FEA of this assembly was simulated and the results used to estimate its useful life. This report gives a detailed acccount of the factors to be considered when performing a FEA and the procedure used to transfer the results to a reliability figure-of-merit.
