“…The geometry of single edge notch tension specimen for Mode I tests [129] is shown in Figure 6(b). It has been used under static [129–131] and impact [73] loading conditions. This type of specimen offers lower stresses in front of crack tip, and thus results in self similar crack propagation and lower failure loads [129,132].…”

Composite materials are known for their high stiffness and strength at lower weight as compared to conventional structural materials. Recently, there has been a growing interest in finding the new ways to decrease delamination failure, which is a life limiting factor of laminated composites. This review paper emphasizes on the effects of different reinforcement structures on mode I fracture toughness and possible ways to improve fracture toughness. A brief description on intrinsic and extrinsic mechanisms of crack growth has been discussed along with the earlier investigations and recent developments for mode I fracture toughness testing. Factors that affect the fracture toughness are also discussed. A brief knowledge of mode I fracture toughness of traditional and advanced fiber-reinforced composites is given, which could help researchers to understand fracture behaviors of composites and thus, it can help engineers to design composites with higher interlaminar strength.

“…Finite element analysis (FEA) is widely used computational method in dental implantology that allows investigators to predict the responses which are challenging to be determined in in vitro and in vivo works especially at the bone-implant interface [13][14][15]. FEA plays an important role in explaining mathematical modelling problems in many fields of science and industry such as through structural, fluid [16,17], thermal, fatigue, and fracture mechanics analyses [18][19][20][21][22].…”

The perseverance of dental implant system in restoration of occlusion is highly dependent on biomechanical overloading factors such as implant macro geometries, parafunctional oral habits, and material. Different implant materials could affect the load transfer at the bone-implant interface differently which is related to stress shielding phenomenon. To date, the role of various implant materials on the surrounding tissues as well as implant stability is still debatable and unclear especially when the implant failure is of concern. Through this study, implant body with different materials or stiffnesses that are zirconia, Ti-6Al-4V, cpTi, TiZr, and PEEK were investigated via 3-D FEA. The bone tissues were modelled based on CT image datasets and subsequently be processed in SolidWorks software. All geometries were converted into finite element models and analysed in ANSYS software. The bone and implant models were assigned with anisotropic and isotropic properties, respectively. A dynamic occlusal loading of 300 N and pretension of 20 N were applied on the implant body and screw, respectively. The results showed that the less stiff implant increased the bone stress and decreased the implant body stress values compared to the stiffer implant. Moreover, the implant with lower stiffness exhibited lower bone strain and higher implant deformation than the implant with higher stiffness. Of all implant materials analysed, PEEK is observed to be the most satisfactory. However, further modifications on PEEK would be necessary to improve inherent bioactivity and osseointegration.

The triaxial woven fabric is known for their light weight and isotropy of mechanical properties. However, researches that using it as reinforcement to form different structural composites were rarely mentioned. Here, we found that the effect of the triaxial woven fabric can be almost equivalent to the unidirectional fabric in flexural strength (99.18%) when it was added as a reinforcing material into the unidirectional fabric composites even though the weight of triaxial woven fabric has only a third of unidirectional fabric. Moreover, the effects and mechanisms are quite different when changing the position of the triaxial woven fabric in the composites. The damage modes of composites when triaxial woven fabric in different stacking sequences were summarized and the resin blocks model from triaxial woven fabric composites was presented in this paper.
