Investigation on the longitudinal compressive strength of unidirectional carbon fiber/nanoparticles reinforced polymer composites using FFT-based method

The longitudinal compressive properties of carbon fiber/nanoparticles reinforced polymer unidirectional composites are investigated by experiments and a series of numerical simulations based on fast Fourier transforms (FFT) method taking into consideration matrix plastic behavior and initial fiber waviness. The efficient and accurate FFT-based method is convenient and has the low computation cost to discuss the effects of material and geometric...
