Specimen no.	Stress–strain curves	\(\overline{\sigma }\) (MPa)
Specimen no.	Stress–strain curves	When the maximum compressive stress exceeds the material yield strength	When calculating divergence
36C1	Concave toward strain axis	− 35.0	− 45.0
36C2	Concave toward strain axis	− 40.0	− 55.0
36C3	Concave toward strain axis	− 65.0	− 70.0
36C4	Concave toward strain axis	− 50.0	− 70.0
