The results of the tensile test.

δ	Tensile stress 𝜎𝑗 MPa	Elongat. 𝜀𝑗 %	Relat. coeffic. of		Frac.
			Tensile stress 𝑐𝑡	Elongat. 𝑐𝑒
𝛿2	415	37.8	0.82	1.11	PZ
𝛿2	413	35.7	0.82	1.05	PZ
𝛿1	488	16.2	0.95	0.49	W
𝛿1	466	11.8	0.91	0.36	W

𝜎_𝑗 and 𝜀_𝑗 are the tensile stress and elongation for joint: 𝑐_𝑡 = 𝜎_𝑗/𝜎_𝑏, 𝑐_𝑒 = 𝜀_𝑗/𝜀_𝑏.
