Scholarcy highlights

  • The investigation of thermal load on the graphene-platelets-reinforced composite is an important issue for developing composite structures in aerospace applications like the spacecraft in near-Sun missions
  • This paper presents vibration and symmetric thermal buckling behaviors of an annular sandwich plate that consists of two asymmetric piezoelectric surface layers and one GPLRC core layer
  • Results reveal that adding graphene-platelets into the matrix can increase the fundamental natural frequency, while decline the thermal buckling temperature
  • The combined action of asymmetric configuration of piezoelectric layers and distribution patterns of graphene-platelets has a significant influence on the vibration and thermal buckling
