Abstract Bio-inspired porous metallic scaffolds have tremendous potential to be used as artificial bone substitutes. In this work, a radially graded lattice structure (RGLS), which mimics the structures of natural human bones, was designed and processed by laser powder bed fusion martensitic Ti-rich TiNi powder. The asymmetric tension-compression behaviour, where compressive strength is significantly higher than tensile strength, observed in material, echoes mechanical behaviour bones....
Auxetic structures have attracted attention in energy absorption applications owing to their improved shear modulus and enhanced resistance indentation. On the other hand, four-dimensional (4D) printing is an emerging technology that capable of 3D smart materials with additional functionality. This paper introduces development a NiTi negative-Poisson's-ratio structure superelasticity/shape memory capabilities for ballistic applications. An analytical model was initially used optimize...
This study presents a thorough experimental investigation utilising the design of experiments and analysis variance (ANOVA) to examine impact machining process parameters on chip formation mechanisms, forces, workpiece surface integrity, damage resulting from orthogonal cutting unidirectional CFRP. The identified mechanisms behind found it significantly orientation fibre tool’s angle, in increased bounceback at larger angles when using smaller rake angle tools. Increasing depth cut results...
The rapid increase in industrial utilisation of carbon fibre reinforced plastic (CFRP) composites recent years has led to growing interest numerical modelling material behaviour and defect formation when machining CFRP. inhomogeneous/anisotropic nature CFRP however presents considerable challenges accurately workpiece defects such as debonding between the matrix phase following cutting operations. Much published literature involved use zero thickness cohesive elements represent fibre-matrix...
Oocyte deformation during injection is a major cause of potential cell damage which can lead to failure in the Intracytoplasmic Sperm Injection (ICSI) operation used as an infertility treatment. speed plays important role creation. In this paper effect different speeds on zebrafish embryos studied using specially designed experimental set-up. An analytical model developed order link force, deformation, and speed. A finite element (FE) also analyse speed, allowing production additional...
Carbon-fibre-reinforced plastic (CFRP) is increasingly being used in various applications including aerospace, automotive, wind energy, sports, and robotics, which makes the precision modelling of its machining operations a critical research area. However, classic finite element (FEM) approach has limitations capturing complexity machining, particularly with regard to interaction between fibre–matrix interface cutting edge. To overcome this limitation, hybrid that integrates smoothed...
