Due to their outstanding mechanical properties and biocompatibility, additively manufactured titanium porous structures are extensively utilized in the domain of medical metal implants. Implants frequently undergo cyclic loading, underscoring significance predicting fatigue performance. Nevertheless, a life model tailored is currently absent. This study employs multiple linear regression, artificial neural networks, support vector machines, random forests machine learning models assess...
Triply periodic minimal surfaces (TPMSs) are known for their smooth, fully interconnected, and naturally porous characteristics, offering a superior alternative to traditional structures. These structures often suffer from stress concentration lack of adjustability. Using laser powder bed fusion (LPBF), we have fabricated Inconel 625 sheet-based TPMS lattice with four distinct topologies: Primitive, IWP, Diamond, Gyroid. The compressive responses energy absorption capabilities the designs...
In this study, we innovatively proposed a deep learning model architecture to address the industry challenges in detection of porosity magnesium alloys. Magnesium alloys, known for their lightweight and high-strength characteristics, are extensively utilized aerospace, automotive, biomedical fields. However, absorption hydrogen during production process leads formation pores, which not only reduce material’s strength durability but may also cause premature failure material. The pores...
Exploring the preparation of multifunctional hydrogels from a bionic perspective is an appealing strategy. Here, hydrogel dressing inspired by characteristics porous extracellular matrix produced during Acomys wound healing prepared. These dressings are printed digital light processing printing composed gelatin methacrylate, hyaluronic acid and pretreated platelet-rich plasma (PRP) to shape out triply periodic minimal surface structures, which freeze-dried for long-term storage. mimic...
Mechanical properties of open-cell titanium foams with different cell geometries (truncated octahedron and rhombic dodecahedron cells) were examined through compressive tests. These manufactured the electron beam melting (EBM) process. The behavior depends on porosity, geometry orientation. Titanium truncated cells showed high strength compared to those cells. This is due short edges in In addition, parallel oblique against compression direction are effective increase strength. Macroscopic...
Porous materials possess light weight and excellent thermal insulation performance. For disordered porous structures, the number of seed points is an important design parameter which closely related to morphology mean pore size structure. Based on arrangement in three-dimensional space, seven kinds structures were designed by spatial Voronoi tessellation this paper. The effect effective conductivity for was studied. Numerical simulation conducted research effects structural porosity, filling...
The effect of fluidity on open cell AZ31 metal foam samples fabricated using a solid state space holder method was investigated. Granule by plaster powder and perlite powder. Granules were sieved which compacted layer in casting mold. Preforms made granules then heated to 200 °C, 300 400 500 °C under rough (mechanical) vacuum before pressure infiltration with Mg alloy. Samples infiltrated values range 8–14 KPa. conditions temperature performed order get different manufacturer specimen...
Porous materials have significant advantages, such as their light weight and good specific energy absorption. This paper presents the designs of two ordered Voronoi structures, a truncated octahedron (Octa) rhombic dodecahedron (Dodeca), based on spatial tessellation. Through numerical analysis, dynamic behavior, deformation absorption porous structures under different impact energies were explored. According to energy-absorption index, effects porosity, rotating unit cell unit-cell shape...

Abstract Silicon carbide fiber‐reinforced SiC ceramic matrix composites (SiC f /SiC CMCs) based on a domestic KD‐SA fiber were exposed to wet oxygen atmosphere for 135 h at 800, 1100, and 1300°C. The evolution of the microstructure mechanical properties CMCs have been systematically investigated following oxidation. For weight change, CMC‐1300 showed greatest gain (0.394%), followed by CMC‐1100 (0.356%) CMC‐800 (0.149%). volatilization boron oxide (B 2 O 3 ) combined with slight oxidation...
