Experimental Investigation and FE Stress Analysis of Adhesive T-Joint with and without Crack in Fluidization Bed

Abstract

In this study, investigation on adhesive T-joint with and without crack in urea granulator fluidization bed was carried out by experiment and finite element (FE) analysis. Specimens with and without crack were made from actual size of 1.25 mm perforated plate to duplicate actual structure of granulator fluidization bed and verified using commercial finite element. The existence of crack will affect the strength of adhesive T-joint. The objectives of this project were to examine a series of adhesively bonded T-joints with and without crack under mode I loading, to identify the effective bond thickness by tensile testing and FE analysis. It was found that result pattern from experiment was in agreement with FE analysis.
