Special Issue Information

Dear Colleagues,

We invite authors to submit original research articles, review articles, and significant preliminary communications in the area of “Mechanical Properties and Characterization of Bonded Composites”. Bonded composites are widely seen in different engineering applications at different length scales including micro-electro-mechanical systems (MEMS), fiber/matrix joints in fiber-reinforced composites, aerospace structures, and civil infrastructures. We are primarily interested in papers addressing mechanical behavior, fatigue, fracture, and damage mechanics at the interface of bonded components including adhesively bonded joints, welded components, etc. Theoretical works with experimental validations and numerical works conducted at different length scales (from atomistic to continuum) are highly encouraged. Contributions with applications in the mechanical and manufacturing, aerospace, civil, biomedical, chemical, and the electrical engineering fields are warmly welcomed. Topics of interests include (but are not limited to):

  • Characterization of the cracking/mechanical behavior of bonded composites
  • Bonded composites under time-independent and time-dependent loading system of external forces/moments (e.g., quasi-static, impulsive, impact, blasting, creep, contact, and fatigue loading)
  • Bonded composites under extreme environments (high/low-temperature, corrosive environments, etc.)
  • Bonded composites made of advanced materials for advanced engineering applications.
  • Developing novel fracture theories in bonded composites using linear-elastic/elasto-plastic fracture mechanics for complex stress concentrators (interface cracks, notches, etc.)
  • Bonded composites processed by additive manufacturing techniques.

Until now, some test specimens with different shapes and loading mechanisms have been utilized for investigating the cracking behavior of adhesive bounded joints. In this research, using a novel test configuration called adhesive short bend beam specimen containing an inclined crack and loaded by three-point bending, mixed mode I/II fracture parameters of a crack initiated in the adhesive part is studied. Compared to other test methods, the specimen used in this research needs a lesser amount of material and the fracture test can be performed easily. A large number of finite element models of this specimen were analyzed using ABAQUS code to study the effect of adhesive and adherent type, and also the crack length and loading span distance on KI, KII, T-stress and fracture initiation direction under different mode mixities. The results showed that the fracture parameters (and in particular the shear mode component) are sensitive to the type and location of adherent in the bounded joint; however, the shape and size of fracture plastic zone is not affected noticeably by the type of adhesive-adherent materials. It was also shown that the complete mode mixities ranging from pure mode I to pure mode II can be introduced for adhesive bounded joints using the proposed test specimen and therefore the specimen is a good candidate test configuration for investigating the mixed mode I/II fracture behavior of adhesive bounded joints.

Asphalt mixture is a type of textured composite material made of aggregates and mastic part. Overall strength and failure behavior in such materials depends on the texture or heterogeneity of the mixture. In particular, the crack growth mechanism from the tip of the pre-crack is significantly affected by the texture of the asphalt composite and environmental conditions. The crack can extend through the soft mastic, tight aggregates or interface of the mastic/aggregates. In this research, by performing some fracture tests on a typical asphalt mixture with different test specimens under mode I, mixed mode I/II and mixed mode I/III, the fracture resistance and trajectory of propagating crack is studied at two low and medium temperatures (i.e., −15 and +15 °C). The load bearing capacity and the fracture resistance of the tested asphalt samples increases by decreasing the temperature. It is also shown that a significant part of fracture plane passes through the soft mastic and boundary of aggregates (i.e., the interface of aggregates and mastic) and only about 10–15% of the fracture surface of the propagating crack passes via the tight aggregates by breaking them. This percentage decreases for mode II and III loading conditions and higher testing temperatures. Compared to brittle and isotropic materials, the fracture path of the asphalt mixture shows more deviation, and this deviation increases for those mixtures containing coarser aggregates in the ligament and tested under medium temperature conditions.
