Multibody dynamics modeling of human mandibular musculoskeletal system and its applications in surgical planning
Many patients suffering from oral and maxillofacial tumors cannot open their mouths wide after mandibular reconstruction surgery. Musculoskeletal multibody modeling could be a valuable tool for predicting pati...

Hysteresis Behaviors of a Bump-Type Foil Bearing Structure with Amended LuGre Friction Model
The gas foil bearing (GFB) has the prospect of application in the nuclear field because of its oil-free lubrication and high-speed as well as high-temperature performance. In this paper, the hysteresis behavio...

Open AccessAn efficient three-dimensional foil structure model for bump-type gas foil bearings considering friction
This paper presents an efficient three-dimensional (3D) structural model for bump-type gas foil bearings (GFBs) developed by considering friction. The foil structures are modeled with a 3D shell finite element...

Embodiment of intra-abdominal pressure in a flexible multibody model of the trunk and the spinal unloading effects during static lifting tasks
The role of intra-abdominal pressure (IAP) in spinal load reduction has remained controversial, partly because previous musculoskeletal models did not introduce the pressure generating mechanism. In this study...

Nonlinear dynamic analysis of supercritical and subcritical Hopf bifurcations in gas foil bearing-rotor systems
The Hopf bifurcation behavior is an important issue for the nonlinear dynamic analysis of gas foil bearing (GFB)-rotor systems. However, there is a lack of detailed study on different types of Hopf bifurcation...

Modeling muscle wrap** and mass flow using a mass-variable multibody formulation
Skeletal muscles usually wrap over multiple anatomical features, and their mass moves along the curved muscle paths during human locomotion. However, existing musculoskeletal models simply lump the mass of mus...

A mass-flowing muscle model with shape restrictive soft tissues: correlation with sonoelastography
Skeletal muscles are always embedded in sheets of connective tissues, which influences muscle biomechanics by sha** the fascicle geometry and encapsulating muscular mass flow. However, existing Hill-type mus...

Self-similar network model for fractional-order neuronal spiking: implications of dendritic spine functions
Fractional-order derivatives have been widely used to describe the spiking patterns of neurons, without considering their self-similar dendritic structures. In this study, a self-similar resistor–capacitor net...

Abstraction and operator characterization of fractal ladder viscoelastic hyper-cell for ligaments and tendons
This study investigates the viscoelastic behaviour of soft bio-fibres in association with their fractal structures. A spring-dashpot fractal network with the self-similar topology, named the Π-type fractal lad...

Open AccessIsokinetic angle-specific moments and ratios characterizing hamstring and quadriceps strength in anterior cruciate ligament deficient knees
This study is intended to find more effective and robust clinical diagnostic indices to characterize muscle strength and coordination alternation following anterior cruciate ligament (ACL) rupture. To evaluate...

A quaternion-based formulation of Euler–Bernoulli beam without singularity
This paper proposes a singularity-free beam element with Euler–Bernoulli assumption, i.e., the cross section remains rigid and perpendicular to the tangent of the centerline during deformation. Each node of th...

A modeling of sliding joint on one-dimensional flexible medium
The dynamic modeling of a sliding joint on a one-dimensional medium, such as a cable or a beam, is studied in this paper. The sliding joint is implemented by positioning it at a moving node on the one-dimensio...
