Abstract: 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 $100^\circ$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.

Keywords: spheroplast, composite, cyclic loading, low-cycle fatigue, damage accumulation.
