Burst Pressure Assessment of Pressure Vessel Using Finite Element Analysis: A Review

The main objective of this paper is to review various types of methods, formulae, and theories used for the calculation of burst strength of pressure vessel. The pressure at which the pressure vessel should burst if all of the specified design tolerances are at their minimum values is called burst pressure. Prediction of burst strength is the very important aspect in the pressure vessel design to avoid any disaster. The present study mainly focuses on various types of factors which tremendously affect the burst strength of pressure vessel.

Three-Dimensional Finite Element Analysis of Human Femur: A Comparative Study

Three-dimensional finite element analysis (FEA) is widely used to generate reliable subject-specific finite element (FE) model using computed tomography (CT) data that accurately predicts information about bone morphology and tissue density. FEA provides detailed information regarding displacement, stress, and strain distributions along the entire bone. CT scan data is widely used to make realistic investigations on the mechanical behavior of bone structures. The purpose of this paper is to create anatomically accurate, three-dimensional finite element models of the right human femur of three male patients of different age groups of 17, 32, and 40 years, respectively, using CT scan data, loaded by physiologic forces, i.e., half-body weight. An average body weight of 70 kg (686.7 N) is assumed for this study, which is shared equally by the lower limbs according to the hip mechanism; hence, a load of 343.35 N (half-body weight analysis of this model will provide data unavailable at this time to orthopedic surgeons, engineers, and researchers) is applied on each right human proximal femur that affects femur during weight bearing action at different angles and to determine the total deformation, equivalent Von-Mises Stress distribution, maximum principal stress distribution, and fatigue tool throughout the whole femur and comparing the results of human orthopedics.

Finite Element Application to Human Humerus Bone: A Biomechanical Study

The purpose of this retrospective study is to evaluate the biomechanical behavior of the human humerus bone under specific boundary and loading conditions. The shape and material properties of the bones are based on the computed tomography (CT) data set, which was obtained from the Medical College, Jabalpur. Here, the Finite Element Analysis (FEA) which has an important significance in the biomechanical research has been used and its purpose in the field of biomechanics is to predict the mechanical behavior of bones; it is also a powerful computational tool that permits accurate structural analysis. Here, an analytical model of human humerus bone is developed to predict the stress and strain distribution developed. In the model, stress values increased with the increase of the axial load. The results of this analysis are helpful for orthopedic surgeons for clinical interest and bone prosthesis.

Biomechanical Analysis of the RP Model of Human Humerus Bone and its Comparison with the Real Proximal Humeral Bone

The goal of this study is to biomechanically evaluate the rapid prototype (RP) model of the human humeral bone and to compare it with the real proximal humeral bone under the similar loading and boundary conditions. Composite bones provide a reliable source of consistent geometry for finite element (FE) models, as they allow for repeatable experimental validation of the FE model, and avoid handling and preservation issues associated with post-mortem specimens. The altered model of the bone can be considered as patient-specific bone geometry and the loading and boundary conditions are applied accordingly.

Finite Element Modeling of Human Femur Using CT Data: A Biomechanical Analysis

Biomechanics is the development, extension, and application of mechanics for the purpose of understanding better the influence of mechanical loads on the structure, properties, and function of living things. Biomechanics focuses on design and analysis, each of which is the foundation of engineering. CT scan data is widely used to make realistic investigations on the mechanical behavior of bone structures using Finite Element Analysis (FEA). The purpose of this paper is to create anatomically accurate, 3D finite element models of the right human proximal femur for 17, 32, and 40-year-old-male patients using individual CT scan data. Thus, allowing the biomechanical analysis of the male right human proximal femur of different age groups loaded under physiologic forces at constant angle of 28°, i.e., at varying body weights of 70 and 75 kg, respectively which is shared equally by the lower limbs, that affect femur during weight bearing acting at different conditions and to determine the total deformation, equivalent Von-Mises stress distribution, maximum principal stress distribution, and fatigue tool throughout the whole femur, and comparing the results. Analysis of this model will provide data unavailable at this time to orthopedic surgeons, engineers, and researchers of human orthopedics.
