An integrated engineering approach for the preliminary design and synthesis of delta robots Open
The design of delta robots poses significant challenges as their mechanical behavior depends on a high number of dimensional parameters and dynamic factors. This is further compounded by the presence of demanding performance requirements, …

A model of the human cornea as a hydrated, fluid-saturated medium Open
We introduce a new model of the human corneal stroma, regarded as a fluid-saturated continuum, able to describe surface flattening and thickness thinning observed in several pathological conditions. In contrast with more common approaches …

An optimal-transport finite-particle method for driven mass diffusion Open
We formulate a finite-particle method of mass transport that accounts for general mixed boundary conditions. The particle method couples a geometrically-exact treatment of advection; Wasserstein gradient-flow dynamics; and a Kullback-Leibl…

Virtual Prototyping of a Novel Manipulator for Efficient Laser Processing of Complex Large Parts Open
Traditional industrial robots offer significant operational flexibility and adapt well to reconfigurable production systems, although they face limitations in applications demanding high motion performance and spatial positional accuracy. …

Fracture as an Emergent Phenomenon Open
The mechanics of fracture propagation provides essential knowledge for the risk tolerance design of devices, structures, and vehicles. Techniques of free energy minimization provide guidance, but have limited applicability to material syst…

Continuum versus micromechanical modeling of corneal biomechanics Open
Two alternative numerical models of the human cornea are used to simulate the mechanical response under the action of a physiological intraocular pressure (IOP). The first model is continuum or macromechanical, considering the stromal tiss…

A discrete-to-continuum model for the human cornea with application to keratoconus Open
We introduce a discrete mathematical model for the mechanical behaviour of a planar slice of human corneal tissue, in equilibrium under the action of physiological intraocular pressure (IOP). The model considers a regular (two-dimensional)…

Modeling the deterioration of the stiffness and of the collagen fibril distribution in a discrete model of the cornea microstructure Open
We present a stochastic approach to model the mechanical deterioration of the reinforcing microstructure of the human cornea. The fundamental structural micro-components of the stroma, collagen and crosslinks, are assembled deterministical…

Use of effective multiscale cohesive models in the simulation of spall in metal plates Open
Ductile fracture of metals is the net result of void nucleation, growth and coalescence mechanisms that operate at the microscale. Optimal scaling analysis provides the analytical form of the effective material law that models the ductile …

A predictive model of UV-A-riboflavin crosslinking treatment on porcine corneas Open
The crosslinking technique (CXL) is an effective low-risk therapeutic treatment of keratoconus and other ectatic disorders of the human cornea. The effect of corneal CXL is to increase the stiffness of the stroma to prevent the progression…

The inclusion of the epithelium in numerical models of the human cornea Open
We present a patient-specific finite element model of the human cornea that accounts for the presence of the epithelium. The thin anterior layer that protects the cornea from the external actions has a scant relevance from the mechanical p…
