We present a biomechanical model based four-dimensional computed tomography (4DCT) simulation method for examining the patient lung deformation induced by respiratory motion, given only one CT scan as an input. First, we model the lung stress-strain behavior using a sophisticated hyperelastic model, and solve the lung deformation problem through finite element (FE) analysis. We introduce robust...

In this work, a two dimensional (2D) finite element foot model was established from magnetic resonance imaging (MRI) of a male subject. The model comprises first medial planar cross-section through the foot, representing the foot in standing posture. For specified external load, the stress and strain distribution field under foot structure are determined. The material characterization of foot s...

The crawling motion of Dictyostelium discoideum on substrata involves a number of coordinated events including cell contractions and cell protrusions. The mechanical forces exerted on the substratum during these contractions have recently been quantified using traction force experiments. Based on the results from these experiments, we present a biomechanical model of Dictyostelium discoideum mo...

The biomechanics of the uterus is studied on a mathematical model based on a shell of ellipsoid of revolution. The myometrium is treated as a homogenous, isotropic and incompressible elastic material using continuum approach and large deformation theory as introduced by Fliigge and Chou [1] and Green and Adkins [2]. The governing equations which are nonlinear differential equations of boundary ...

In this paper, the development of a large-displacement large-strain 3-D finite element model of the vocal fold is reported. A fold is discretized into 720 8-node brick elements with a total of 1001 nodes and 3003 displacement degrees of freedom. The structure has realistic dimensions and geometry. The model includes geometric and material nonlinearities. The geometric nonlinearity appears in th...

For years, automotive engineers have been working to improve vehicle safety by using dummies, human corpses and animals to test safety systems. However, in most cases, crash tests do not consider drivers differences, much less their reactions. In reality, no one can make real crash tests with living drivers. Current approach is to simulate crashes using a driving simulator to analyze driver’s b...

The foot is modeled as a statically indeterminate structure supporting its load at the heads of the five metatarsals and the tuberosity of the calcaneous. The distribution of support is determined through an analysis of the deformations caused in the structure as a result of the forces at these locations. The analysis includes the effect of the plantar aponeurosis and takes into account the def...

The dynamic analysis of the biomechanical model of the head load impact using the Differential Transform Method is presented in this paper. In many parts of the world, the problem of traumatic brain injuries (TBI) has led to neurodegenerative dementing disorders and diseases as a result of head load impact from sporting activities, accidents involving the head, etc. have serious effects on huma...

The modern biomechanical two-phase poroelastic model of bone tissue is presented. Bone tissue is treated in this model as a porous elastically deformed solid filled with a viscous newtonian fluid. Traditional one-phase biomechanical model of bone tissue, which is characterized by the Young modulus and the Poisson's coefficient, is still valid and it can be treated as an approximate model in com...

Squat exercise is acquiring interest in many fields, due to its benefits in improving health and its biomechanical similarities to a wide range of sport motions and the recruitment of many body segments in a single maneuver. Several researches had examined considerable biomechanical aspects of lower limbs during squat, but not without limitations. The main goal of this study focuses on the anal...
