In this study, an isoparametric micro‐mechanical model is developed to study the failure behaviors under biaxial loadings for composites with different fiber arrangements. For validating the method, the numerical results of the unidirectional (UD) composite lamina with consideration of two different failure criteria (the constituent failure criterion and UD failure criterion) are compared with the...
the DFH (Differential Frequency Hopping) technology brings high performances for HF (Frequency Hopping) communication systems. Symbol-by-symbol detection has been widely used in DFH systems, but the anti-jamming (AJ) performance is poor. In order to achieve better AJ performance, a novel anti-jamming technique based on Correlation Pre-Windowing Filter (CPWF) on frequency domain is proposed in this...
