Maximum stress on insulated glass under different working conditions.

W (kg)	r (m)	(MPa)	σ1 (N·mm^−2)	σ2 (N·mm^−2)	State of glass (the results of experiment)
0.1	1.0	0.870	60.840	55.860	Intact
	0.9	1.116	66.798	61.405	Intact
	0.8	1.461	74.007	68.141	Intact
	0.7	1.962	82.893	76.483	The layer face to the explosion wave front is broken, and the back is intact
	0.6	2.727	94.204	87.054	The layer face to the explosion wave front is broken, and the back is intact
	0.57	3.035	98.395	90.789	The layer face to the explosion wave front is broken, and the back is intact
	0.54	3.393	102.961	95.020	The layer face to the explosion wave front is broken, and the back is intact
	0.52	3.665	106.238	98.110	Both the layers of glass are broken
	0.50	3.968	109.719	101.340	Both the layers of glass are broken
