“…These damage parameters were obtained by comparing experimental and simulation results [106]. F. Xu et al [109] used clinched joints to assess the predictive accuracy of the constitutive model and compare force-displacement deformation, shape of clinched joints and fracture location to further optimise the constitutive model as shown in Figure 8. They also used the orthogonal analysis method [25] to determine the range of the damage parameters.…”

“…They also used the orthogonal analysis method [25] to determine the range of the damage parameters. F. Xu et al [109] agreed that the modified Rousselier damage model can be used to predict the clinching process to propose a new experimental specimen to calibrate the damage constitutive model. Unfortunately, no research institution has compared the difference between the modified GTN damage model [80] and the modified Rousselier damage model [81], especially for predicting the clinching process and failure behaviour.…”

“…A preliminary estimate of the strain-hardening exponent N was obtained by the least-squares fit of the small strain data. F. Xu et al [109] used the model of Z. Xue et al [115] to fit the hardening equation through segmentation functions as shown in Equation (11).…”

The clinching technology attracted increasing attention in recent years, but its application might be restricted due to the growing employment of materials that are difficult to join and hybrid structures involving different mechanical performance materials. Traditional clinching technology has limitations of strain rate sensitivity, ductility and damage fracture when applied to materials with high strength, low strain-to-failure and low plasticity. However, the ductility and formability of the material represent a limitation for the clinching process. The present study explored some concepts of clinching, such as hole, friction-assisted, laser-assisted, electro-hydraulic, electromagnetically assisted and hot assisted clinching, for the difficult-to-form sheets. The paper includes the description of the deformation mechanism of clinched joints and the analysis of clinched joint performance and applicability.

“…The purpose of the optimisation of parameters during SPS moulding was to reach the maximum conductivity. Orthogonal design is a kind of design method that is primarily used to study multiple factors and multiple levels [ 44 ]. The suitable level range reduces the number of optimisation design alternatives.…”

Polymer-composite materials have the characteristics of light weight, high load, corrosion resistance, heat resistance, and high oil resistance. In particular, graphene composite has better electrical conductivity and mechanical performance. However, the raw materials of graphene composite are processed into semi-finished products, directly affecting their performance and service life. The electromagnetic pulse compaction was initially studied to get the product Graphene/PEKK composite powder. Simultaneously, spark plasma sintering was used to get the bars to determine the electrical conductivity of Graphene/PEKK composite. On the basis of this result, conducting Graphene/PEKK composite powder can be processed by electromagnetic pulse compaction. Finite element numerical analysis was used to obtain process parameters during the electromagnetic pulse compaction. The results show that discharge voltage and discharge capacitance influence on the magnetic force, which is a main moulding factor affecting stress, strain and density distribution on the specimen during electromagnetic pulse compaction in a few microseconds.

“…The Gurson-Tvergaard-Needleman (GTN) damage model [21] is a ductile failure criterion which has been used to study failure mechanism in many metals [22][23][24][25], including titanium alloys [26][27][28]. The GTN model considers nucleation, growth, and coalescence of micro-voids and void volume fraction, which can give a suitable view of the damage in a material [29].…”

In this study, a micromechanical finite element model is proposed based on experimental data and the rule of the mixture (RoM) in order to predict the tensile behavior of mechanical properties of heat-treated dual-phase medical-grade titanium (Ti–6Al–4V). Tensile tests, micro-hardness measurements, and RoM were used to obtain flow curves for the α and β phases. Scanning electron microscopy (SEM) imaging was used to determine phase fractions and to create representative volume elements (RVEs). Furthermore, the Gurson-Tvergaard-Needleman (GTN) damage model was calibrated using the Taguchi design of experiment (DOE) method in order to predict damage in the microstructure and the results were compared to fracture surface obtained using fractography in order to investigate failure mechanisms. The final micromechanical model could accurately predict stress-strain curves and showed that void formation and coalescence is the primary mechanism of failure. Finally, analyses of the surfaces showed that a fully ductile fracture occurs at the failure point, which agrees with the results of the damage model. The results suggest that the proposed model can predict the failure of heat-treated Ti–6Al–4V bio-alloys.
