Chapter
Micromachined gyroscopes are beginning to compete with their macro-scale counterparts in terms of performance. This has been made possible because of a remarkable design change that has come to be known as a Disk Resonator Gyroscope (DRG). The design of a DRG can be thought of as an extension of the Ring Resonator Gyroscope (RRG) or vibratory ring...
Article
Pelvic bone is a complex and robust load-bearing skeletal structure in the human body, the evolution of which might have been influenced by mechanical loads of daily activities like walking, upright standing, and running. Since the main function of skeletal bones is to provide rigidity to the body and provide hard surfaces for muscle attachment as...
Article
This work aims to design a prosthesis of the pelvic bone considering the effect of muscle forces using principles of structural topology optimization. The running gait cycle is chosen since it has high active muscle forces and is divided into seven phases. The pelvic prosthesis is designed for individual seven phases with non-design domains. Materi...
Article
Hip bone is a robust and complex skeletal structure in the human body and it bears loads while doing the daily activities such as walking, running, etc., by connecting the leg with the torso. The geometry of the hip bone facilitates upright gait in humans and hence its evolution might have been influenced by the mechanical forces acting on it. Prev...
Chapter
Resonance occurs when the natural frequency of the system matches with the vibrating frequency. It may cause structural instabilities. To avoid this, engineers maximize the first natural frequency of the system. In many applications, the natural frequency is pre-designed. Structural engineers aim to reduce the weight of structures subject to functi...
Conference Paper
In this work, we use structural topology optimization to design the hip bone with multi-load conditions of walking gait cycle. Previous research works on optimal bone design primarily aimed to design the micro-structure of the femur bone using a multi-load approach with global geometry fixed. To the best of authors' knowledge, no optimal design res...

This work presents a topology optimization based approach towards the optimal design of the human hip bone under mechanical loads during walking. The human hip bone is a complex structure that connects the leg with the torso. It transfers body loads from the upper body to the leg during standing, walking , running, and other daily activities during...
Chapter
Topology optimization is a method to find the optimal material distribution of a structure by minimizing the objective function under the design and limit constraints. In this paper, we developed a deep learning-based machine learning algorithm to get the optimized structure for the given input conditions of a structure. We trained convolutional ne...
Chapter
Shape Optimization is a method to find the optimal shape of a structure by minimizing the objective function i.e, volume and/or compliance under the design and limit constraints. The boundary of the structure is discretized using B-Splines which allows local control and these control points are taken as design variables for the optimization formula...
Conference Paper
Pelvic reconstruction is required to restore the functional activity after an internal hemipelvectomy. The available pelvic prosthesis has several complications and long terms issues (such as stability, dislocations etc.) due to non inclusion of the basic mechanics. In this study, a structural optimization based pelvic design is presented for an ef...
Chapter
Structural topology optimization finds the optimal material distribution in the given domain by optimizing the objective function subject to the loading and boundary constraints. Solid Isotropic Material Penalization (SIMP) method is widely used to solve topology optimization due to its simplicity in implementation but the resulting optimal design...

Topology Optimization (TO) is a method to find the optimal material distribution of a structure by minimizing the objective function under the design and limit constraints. In this paper, we developed a deep learning based machine learning algorithm to get the optimized structure for the given input conditions of a structure. We trained Convolution...
