“…Rebiere et al [9] presented an energetic criterion to model initiation and propagation of matrix cracking and delamination in composite cross ply laminates. Moreover, Pavia et al [10] used an energy analysis to predict the matrix cracking stress as a function of relevant material parameters. Van der Meer et al [11] presented a finite element model using the phantom node method for matrix cracking and interface elements for delamination.…”

The composite materials are nowadays widely used in aeronautical domain. These materials are subjected to different types of loading that can damage a part of the structure. This diminishes the resistance of the structure to failure. In this paper, matrix cracking and delamination propagation in composite laminates are simulated as a part of damage. Two different computational strategies are developed: (i) a cohesive model (CM) based on the classical continuum mechanics and (ii) a continuous damage material model (CDM) coupling failure modes and damage. Another mixed methodology (MM) is proposed using the contin uous damage model for delamination initiation and the cohesive model for 3D crack propa gation and mesh openings. A good agreement was obtained when compared simple charac terization tests and corresponding simulations.

“…The theoretical analysis of PLS can be divided into two cases, i.e., the energy balance approach, including the ACK model [18], BHE model [19], SH model [20], and Chiang model [21][22][23], and the stress intensity factor approach, including MCE model [24], MC model [25], and Chiang model [26]. Pavia et al [27] predicted the PLS in micro/nanohybrid brittle matrix composites based on the ACK shear-lag model. It was found that the presence of a small function of strong stiff nanotubes provides significant enhancements in the PLS.…”

AbstractIn this paper, the temperature-dependent proportional limit stress (PLS) of SiC/SiC fiber-reinforced ceramic-matrix composites (CMCs) is investigated using the micromechanical approach. The PLS of SiC/SiC is predicted using an energy balance approach considering the effect of environment temperature. The relation between the environment temperature, PLS, and composite damage state is established. The effects of the fiber volume, interface properties, and matrix properties on the temperature-dependent PLS and composite damage state of SiC/SiC composite are analyzed. The experimental PLS and interface debonding length of 2D SiC/SiC composites with the PyC and BN interphase at elevated temperatures are predicted. The temperature-dependent PLS of SiC/SiC composite increases with the fiber volume, interface shear stress and interface debonding energy, and the matrix fracture energy and decreases with the interface frictional coefficient at the same temperature.

“…They have been used widely in electronics, biotechnology, chemistry, and composites [4,5]. The reinforcing effect of carbon nanotubes in concrete is expected to be very large [6][7][8]. Carbon nanotubes can be differentiated from traditional concrete reinforcing fibers that are used as stiffeners in high-strength/high-performance concretes [4,[8][9][10].…”

The effect of carbon nanotube content (0, 0.5, 1.0, 1.5, and 2.0% of the cement weight) on the bonding properties of macrosynthetic fiber in latex-modified hybrid fiber cement-based composites (LMHFRCCs) was evaluated. The slump value, compressive strength, and bonding strength were measured for each LMHFRCC. As the carbon nanotube content increased to 1.5%, the bonding properties of the macrosynthetic fiber improved. However, the bonding performance deteriorated at a carbon nanotube content of 2.0%. A decrease in the fluidity of the mix negatively affected the dispersion of the nanotubes in the LMHFRCCs. The addition of carbon nanotubes also affected the relative bonding strength independently of the improvement in compressive strength. Microscopic analysis of the macrosynthetic fiber surfaces was used to understand changes in the bonding behavior.
