Abstract;Stress and deformation of cathode ray tubes (CRTs) under atmospheric pressure and implosion protection band tightening were analyzed using a finite element method (FEM). The stress and deformation of the tubes were measured experimentally by using strain gages and three-dimensional position measuring techniques. The experimental results showed close agreements with those of the simulation. The location of the highest tensile stress and the effects of tightening of the implosion protection bands on the stress and deformation of the tube were clarified. Long-term reliability of the tubes were also studied by using these simulation techniques and the strength characteristics of the CRT glass taking account of surface roughness and delayed fracture.
