This work reviews the main techniques to model dynamical systems with contact-impact
events. Regularized and non-smooth formulations are considered, wherein the fundamental …

Over the past decade, there has been a rapid increase in applications of multibody system
dynamics to the predictive simulation of human movement. Using predictive “what-if” human …

The nature of the constitutive contact force law utilized to describe contact–impact events in
solid contact interfaces plays a key role in predicting the response of multibody mechanical …

A biofidelic multibody model of the upper limb for the quantitative assessment of joint
kinematics and dynamics has the potential to become an innovative tool in many application …

Computational prediction of 3D crutch-assisted walking patterns is a challenging problem
that could be applied to study different biomechanical aspects of crutch walking in virtual …

Abstract According to the World Health Organization, 15% of the world's population lived
with some form of disability in 2011 and, nowadays, more than one billion people worldwide …

Foot–ground contact models are an important part of forward dynamic biomechanic models,
particularly those used to model gait, and have many challenges associated with them …

The paper aims to theoretically show the feasibility and efficiency of a passive exoskeleton
for a human walking and carrying a load. The human is modeled using a planar bipedal …

Passive dynamic walking is a manner of walking developed, partially or in whole, by the
energy provided by gravity. Studying passive dynamic walking provides insight into human …

The paper presents a full account of Poisson's impact law in inequality form. Based on an
entirely new setting for the decompression phase, impact laws for unilateral and bilateral …
