Experimental Study of Glass Strength against Shock Wave Loading-Stress Generation of Float Glass Plates-

摘要

Stress generation of shock wave on a 300 mmX300 mm float glass specimen was investigated.Stresses in float glass plate increased to a maximum value impulsively,and decayed accompanied by a periodical oscillatory pattern.The stress values sigma so far generated can be written in the following form of time t and thickness d using 4 parameters,sigma(t,d~*)=C_d sin omegat·exp{-gamma (t-pi/2omega)}+C_s.In these 4 parameters C_d and C_s are showed as a factor of Mach number by normalizing with glass thickness,and lambda and omega are dependent on glass thickness.
