Deformation and fracture of a spheroplast under low-cycle loading at various temperatures

This paper gives the results of an experimental study of the deformation and fracture of a spheroplast under uniaxial low-cycle loading (compression and unloading) at a temperature T = 25 and 100°C. Various mechanisms of damage accumulation at various temperatures and degrees of damage to the material are studied. The experimental results are compared with the well-known dependences taking into account damage accumulation for metals. It is established that the basic propositions of these theories are suitable for the low-cycle fracture of spheroplast — a ductile material of complex structure. __________ Translated from Prikladnaya Mekhanika i Tekhnicheskaya Fizika, Vol. 50, No. 1, pp. 197–204, January–February, 2009.
