In the design of many structures, a particular area of concern is exposure to seismic and wind-induced vibrations. Viscoelastic structural dampers have been implemented into structural layouts as a means to limit the strain and decrease the risk of failure in building components due to such excitations.

Safe and cost-effective drilling is a major issue in the oil and gas industry. In addition to the common prospecting risk, the borehole itself provides uncertainties that are not desired, but unavoidable. Today, we would like to show how numerical simulations can help here. The goal is to predict the stability of an open-hole multilateral well for deciding if the well will need expensive mechanical stabilization — or not.

The chemical industry is considerably important to economies around the world, playing a critical role in processes ranging from the production of clean drinking water to the manufacture of pharmaceutical products. Chemical engineers are faced with the challenge of ensuring profitability in a rapidly growing and evolving market. Packed bed reactors are one of the most common reactors used in the chemical industry due to their high conversion rate per catalyst weight compared to other catalytic reactors.

Diabetes is an incurable global killer: the World Health Organization estimates 350 million diabetics worldwide, with an average annual fatality rate close to 1%. Fortunately, modern medical science enables diabetics to manage their glucose levels and intake, so many countries have seen greatly reduced danger of the disease. Many diabetics must track their glucose levels throughout the day, requiring an accurate method for measuring the concentration of glucose in blood. For modern sensor designs, the method of choice is electrochemistry.

Today, we invite guest blogger Nagi Elabbasi of Veryst Engineering to share the work they performed on simulating wear in COMSOL Multiphysics. Using COMSOL Multiphysics, we implemented a wear model and validated it by simulating a pin-on-disc wear test. We then used the model to predict wear in an automotive disc brake problem. The results we found showed good agreement with published wear data.

In the past, we have discussed the importance of material selection in 3D printing and how it can affect the integrity of the final product. With advancements in technology, the industry has evolved from the production of more simple materials, like plastics, to those of greater difficulty, such as metals. Here, we take a more in-depth look at 3D metal printing and its potential to revolutionize the manufacturing process.
