“…Therefore, to improve the TSR of ceramic materials and explore the mechanism of thermal shock damage of ceramic materials has become a key problem to be solved urgently. Many researchers have used experiments, theories, and numerical simulation methods to study the thermal shock behaviors of ceramics and discuss the TSR of ceramics, and they have achieved important results (Cui et al, 2021b;Zhang et al, 2022).…”

Thermal shock is one of the main causes for the fracture of ceramic materials due to their inherent brittleness. Aiming to explore the mechanism of thermal shock cracking behavior of ceramics under different thermal shock conditions, a novel temperature-dependent failure criterion of thermal shock fracture of the ceramic materials was deduced based on the force-heat equivalence energy density principle. Combining this failure criterion and the finite element method, the thermal shock cracking behaviors of the thin circular and rectangular ceramic slabs under different thermal shock initial temperature were simulated. Results show that the morphology, periodicity, hierarchy, and number of thermal shock cracks obtained by numerical simulation are in good agreement with the experimental results. These essential characteristics verify the validity of the temperature-dependent failure criterion for thermal shock fracture. Furthermore, the strain energy of tension produced by thermal shock is proved to be the dominated mechanism for thermal shock-induced fracture.

“…In the field of coating techniques, several methods of deposition are mentioned, such as atmospheric plasma spraying, physical and chemical vapour deposition (PVD and CVD processes) [8]. In addition, in order to increase the bonding strength between coating and alloy substrate, thermal spraying technology is considered to be an effective coating preparation method, such as hot dip method [25,26], chemical vapor deposition method [27,28], slurry method [29,30], etc.…”

Biomimetic Deposition of Hydroxyapatite Layer on Titanium Alloys

Over the last decade, researchers have been concerned with improving metallic biomaterials with proper and suitable properties for the human body. Ti-based alloys are widely used in the medical field for their good mechanical properties, corrosion resistance and biocompatibility. The TiMoZrTa system (TMZT) evidenced adequate mechanical properties, was closer to the human bone, and had a good biocompatibility. In order to highlight the osseointegration of the implants, a layer of hydroxyapatite (HA) was deposited using a biomimetic method, which simulates the natural growth of the bone. The coatings were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), micro indentation tests and contact angle. The data obtained show that the layer deposited on TiMoZrTa (TMZT) support is hydroxyapatite. Modifying the surface of titanium alloys represents a viable solution for increasing the osseointegration of materials used as implants. The studied coatings demonstrate a positive potential for use as dental and orthopedic implants.

“…The decrease arises due to reduced carbon content caused by oxidation and diffusion processes in the heated state of the band edges [ 45 ]. The diffusion of carbon at interfaces can also be observed in other high temperature processes [ 46 , 47 ]. Since oxidation and diffusion processes were not modeled in the simulation, the local decrease of the hardness in the bonding line cannot be captured by means of FEM.…”

Numerical Simulation of Tube Manufacturing Consisting of Roll Forming and High-Frequency Induction Welding

et al. 2022

View full text Add to dashboard Cite

This paper presents a fully coupled three-dimensional finite element model for the simulation of a tube manufacturing process consisting of roll forming and high-frequency induction welding. The multiphysics model is based on the dual mesh method. Thus, the electromagnetic field, the temperature field, the elasto-plastic deformation of the weld bead, and the phase transformations within the material can be simulated for a moving tube without remeshing. A comparison with measurements shows that the geometry of the welded tube and the weld bead, the force on the squeeze rolls, the temperature along the band edges, and the hardness distribution within the heat-affected zone can be simulated realistically.
