Paper Mechanics and the Benefits of Modeling Paperboard Formation

Guest Eric Linvill January 31, 2019

Guest blogger Eric Linvill of Lightness by Design shares how materials modeling provides insight into paperboard formation and bending resistance. Formation is a fundamental physical characteristic of paper that can have profound effects on the production and performance of that paper. The finite element method can be utilized to better understand how formation affects mechanical quality control tests and their results. Using the Lorentzen & Wettre (L&W) bending resistance (15°) test, we investigate how paperboard formation affects bending resistance.

Cables provide power to sky-high airplanes, underground mines, and offshore wind farms. Depending on the use case, cables can have vastly different shapes, sizes, and environments — all of which affect their performance. In his keynote talk at the COMSOL Conference 2018 Lausanne, Adrien Charmetant of Nexans explained how multiphysics modeling is used to optimize cable designs. Below, you can find a summary and video of his presentation.

How can teachers improve student learning in undergraduate science, technology, engineering, and mathematics (STEM) courses? To find out, Ivana Milanovic, a professor at the University of Hartford, developed a simulation-based approach that combines problem-based learning (PBL) and inquiry-based learning (IBL). Milanovic discussed her strategy and its benefits during her keynote talk at the COMSOL Conference 2018 Boston. Below, you can find a summary and video recording of her presentation.

Radioactive materials have a long half-life, so they must be stored safely — usually in steel drums. These drums are then stored in confinement systems, which are designed with safety in mind (so that they can resist, for instance, a fire event exceeding two hours). Sogin, the state-owned company responsible for the Italian nuclear sites decommissioning and radioactive waste management, evaluated the fire resistance of a confinement system overpack using the COMSOL Multiphysics® software.

When it comes to synchrotron light sources, brighter is better. By using bright beams in their accelerator, researchers at the Advanced Photon Source (APS) synchrotron facility can efficiently gather detailed data. In collaboration with APS engineers, Nicholas Goldring of RadiaSoft LLC creates and distributes simulation applications for designing vacuum chambers relevant to the APS. Below, find a video recording and summary of his keynote talk from the COMSOL Conference 2018 Boston.

Lightning risk is an important consideration in various industries, including aircraft and wind turbines. But how do you study the behavior of a phenomenon that can cause extreme damage in microseconds? And how do you make sure your product can withstand a lightning strike? In his keynote talk at the COMSOL Conference 2018 Boston, Justin McKennon of NTS Lightning Technologies answers these questions, discussing how multiphysics simulation helps in the design and certification of lightning protection systems.

Heart failure is a global health concern, affecting millions of people and keeping them from their everyday lives. But what if there was a device that could keep patients’ hearts pumping and even improve their quality of life? In his keynote presentation at the COMSOL Conference 2018 Boston, Freddy Hansen from Abbott Laboratories discussed a heart pump that could do just that. If you missed his talk, you can watch a recording of the video and read a summary below.

During routine exams, eye care professionals look for common refractive errors like nearsightedness, farsightedness, and astigmatism. As patients age, doctors also look for presbyopia, a loss of the accommodative amplitude that results long-term in a complete loss of the near vision. The visual accommodation process is complex, and useful eye properties needed to improve diagnosis and presbyopia treatment are difficult to obtain. To address the problem of measuring the refractive index of the lens, researchers developed a reverse engineering technique […]
