摘要
The mechanical behavior of sandwich composite materials in fatigue loading is investigated. Fatigue tests in three-point bending were conducted on two types of sandwich materials, [04] and [0/902/0]. The rupture mode observed on tested specimens showed a debond between the core and skins, as well as cracks in the core at 45∙ to the neutral axis of sandwich. Degradation of the rigidity modulus in fatigue was determined from the deflection equation for the two sandwiches. The experiments revealed that the modulus of the [04] sandwich degraded faster than that of [0/902/0]. The evolution of shear modulus in fatigue of both sandwiches is also described analytically using exponential and polynomial models.
