The management and prognosis of aortic dissection (AD) is often challenging the use personalised computational models being explored as a tool to improve clinical outcome. Including vessel wall motion in such simulations can provide more realistic potentially accurate results, but requires significant additional resources, well expertise. With translation final aim, trade-offs between complexity, speed accuracy are inevitable. present study explores whether modelling worth expense case AD,...

Anatomical Landmark detection in CT-Scan images is widely used the identification of skeletal disorders. However, traditional process manually detecting anatomical landmarks, especially three dimensions, both time-consuming and prone to human errors. We propose a novel, deep-learning-based approach automatic 3D landmarks CT lower limb. generate multiple view renderings scanned limb then integrate them, using pyramid-style convolutional neural network, build model bone determine spatial...

Triply periodic minimal surface (TPMS) structures are architectures that possess unique geometrical features, like a smooth and zero‐mean curvature. This article proposes two novel multivoid TPMS shell network structures, namely, IP iBP based on I‐WP, Primitive, iBase architectures. A voxel‐based approach is employed as numerical homogenization method to calculate the mechanical thermal properties of structures. LCD 3D printing for experimental validation which demonstrates close agreement...

An inherent shortcoming of generic musculoskeletal models is their inability to accurately model deformed system, while generating fully personalized are time and money consuming. To address this, we created a MATLAB tool that modifies OpenSim models, producing semi-personalized models. A subject with varus deformity participated in our study her associated was created. The significantly decreased marker error during Inverse Kinematics (p < 0.05). Notably, hip abduction/adduction ROM...

This article describes an investigation into the contact behaviour of polymeric gear transmissions using numerical finite element (FE) and analytical techniques. A polymer pair was modelled analysed ABAQUS software suite results were calculated BS ISO 6336 rating standard. Before describing results, principles strategies methods employed in building FE model have been discussed. The dynamically simulated a range operating conditions. simulations showed that kinematic gears is substantially...

Laser shock peening (LSP) is one of the modern surface treatment methods in which work-piece peened using short and intense laser pulses. In this process, favorable compressive residual stresses are induced on near material. This process usually used to improve fatigue life component has been applied different industries such as aerospace, automotive, nuclear, medical, etc. Many researchers have finite element method (FEM) simulate LSP. majority conducted researches, results good agreement...

The desirable properties of natural porous materials have inspired humans to design cellular with remarkable such as high energy absorption, acoustic and thermal insulation, specific strength structures. Triply Periodic Minimal Surface (TPMS) structures are particularly important among the architected materials. In this research, we developed a novel approach based on genetic algorithm for geometry modification TPMS is exploited enhance effective mechanical structures, namely Primitive, IWP,...

We report a coupled in-situ micro-Laue diffraction and nano-indentation experiment, with spatial time resolution, to investigate the deformation mechanisms in [001]-oriented single crystal MgO.

Abstract The onset of fretting fatigue is characterized by material microstructural changes in which the extent damage comparable to grain size, and hence, microstructure characteristics could have a significant effect on crack initiation. In this paper, three‐dimensional finite element crystal plasticity framework presented for simulation fatigue. Controlled Poisson Voronoi tessellation (CPVT) method employed generate polycrystalline region. CPVT method, regularity parameter controls shape...
