## Digital Debunking: Can You Actually Shatter Glass with Your Voice?

Setting the Stage An opera singer hits a high note, rattling the audience’s ear drums and exploding a wine glass in the drawing room. You may have seen this in the movies, but is this really possible with sound alone? …

## Solving the Geometry Problem: Simulation-Driven Design

Over the years, computer-aided design (CAD) system geometry has evolved…from wireframes to surfaces to solids, and parametric to direct. Simulation, however, remains stuck using the same old beam, shell or simplified-solids paradigm invented more than 50 years ago. As CAD …

## Benchmarking by FEA: Best Practices & Key Quality Checks to Verify Results Accuracy

This guest contribution on the Altair blog is written by the ESRD team, a member of the Altair Partner Alliance With the increased usage of finite element analysis (FEA) software tools for virtual prototyping of new and/or modified engineering designs, and the …

## Investigation of Thermal Stability in Laser Beam Melting

This guest contribution on the Altair Blog is written by the Additive Works Team. Additive Works is a member of the Altair Partner Alliance. More lasers. More power. Higher build rates and lower costs per part. This is the main expectation …

## The Brennan’s Last Stand: Optimizing a Tree Stand that will Last with Altair Inspire

Before the holidays, I shared the process of analyzing my family’s Christmas Tree stand as an example of using Inspire as a FEA tool. The loads and supports that I found to be the most realistic can be seen in …

## Altair Inspire Finite Element Analysis of a Christmas Tree Stand

Every year on the Friday following Thanksgiving, The Brennan family ventures out to a tree farm and gets the biggest pine tree we can find to fill our family living room. Our trees usually range from 14-17 feet tall and …

## 2 + 2 = 3.5, 4 and 6.8? – Standardizing Strength Assessment of Metal Parts

Admitting that the headline is somewhat provocative, this is the exact situation in strength assessment of components made of metals. One might think that the task of evaluating the mechanical strength of a component should be a mundane thing since …

## Saving Lives with Simulations: CEDREM Collaborates with DuPont on Ballistic Protection Solutions

Understanding behind-armor blunt trauma is important for developing effective personal ballistic protection solutions. Even if a bullet is stopped by the armor, some damage can still be transmitted to the body. By today’s standards, the protections are assessed on plastilina blocks …

## Don’t Let the Ocean Knock You Down

Subsurface mooring deployment, recovery, and performance in current and waves For many years moorings have been designed using basic mass-drag-buoyancy calculations, spreadsheets, rules-of-thumb, black magic scripts, and a dose of ‘salty-sea-dog’ experience. With these methods, we can frequently estimate a …
