Damage accumulation and failure in random fiber networks is of importance in a variety of
applications, from design of synthetic materials, such as paper and non-wovens, to …

Existing beam contact formulations can be categorized in point-to-point contact models that
consider a discrete contact force at the closest point of the beams, and line-to-line contact …

Many materials have a network of fibers as their main structural component and are referred
to as network materials. Their strength and toughness are important in both engineering and …

The stochastic variations in the structural properties of thin fiber networks govern to a great
extent their mechanical performance. To assess the influence of local structural variability on …
