Musculoskeletal Mechanics and Modeling

Finite Element Modeling in Musculoskeletal Biomechanics

Numerical approximation of the solutions to continuum mechanics boundary value problems, by means of finite element analysis, has proven to be of incalculable benefit to the field of musculoskeletal biomechanics. This article briefly outlines the conceptual basis of finite element analysis and discusses a number of the key technical considerations involved, specifically from the standpoint of e...

Inference of computational models of tendon networks via sparse experimentation

This dissertation presents novel computational methods to infer accurate functional models of musculoskeletal systems from minimal experimental data focussing on the tendon networks of the human fingers as an example. State of the art biomechanical modeling consists of assuming a fixed structure to the system being modeled and measurement or regression of specific parameter values. However, the...

Institute of Mechanics Modeling of inflatable dams partially filled with fluid and gas considering large deformations and stability

Adaptive surrogate modeling for efficient coupling of musculoskeletal control and tissue deformation models.

Finite element (FE) modeling and multibody dynamics have traditionally been applied separately to the domains of tissue mechanics and musculoskeletal movements, respectively. Simultaneous simulation of both domains is needed when interactions between tissue and movement are of interest, but this has remained largely impractical due to the high computational cost. Here we present a method for th...

Springback Modeling in L-bending Process Using Continuum Damage Mechanics Concept

Springback is one of the most common and important issues in metal forming area. Due to the fact that springback depends on a variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) on springback was investigated based on the Lemaitre isotropic unified damage law. Swift’s hardening law was employed to describe isotropic hardening behavi...

Articular Contact Mechanics from an Asymptotic Modeling Perspective: A Review

In the present paper, we review the current state-of-the-art in asymptotic modeling of articular contact. Particular attention has been given to the knee joint contact mechanics with a special emphasis on implications drawn from the asymptotic models, including average characteristics for articular cartilage layer. By listing a number of complicating effects such as transverse anisotropy, non-h...
