Piezoelectric devices surround us in our everyday life. Our cars and trucks contain many piezoelectric devices, including fuel level sensors, air bag deployment sensors, parking sensors and piezoelectric generators in the wheels to power the tire pressure monitoring system. Your smartphones or tablet contains piezoelectric sensors that detect the motion and orientation of the device, which my kids were using to good effect to play “Need For Speed” yesterday. Many of us have ink jet printers at home, which can use piezoelectric printer heads to eject thousands of drops per second. Continue reading
Cell-culture bioreactors lie at the heart of the processes used to produce large-molecule, protein-based therapeutics. In cell culture, mammalian cells are grown outside the human/plant body. These cells produce therapeutic proteins and antibodies. This is much easier said than done. In fact, cells do not cooperate much when they are grown outside the (human or plant) body. The question then is: Why is it so difficult for cells in culture to have the same physiological function in laboratory as in our body? Continue reading
The U.S. Environmental Protection Agency (EPA) recently released new Corporate Average Fuel Economy, or CAFE standards for light duty cars and trucks. These standards are designed to reduce greenhouse gas emissions and improve fuel economy, leading to model year 2025 vehicles that will emit just one-half the greenhouse gasses that model year 2010 vehicles do.
To reach these ambitious goals, the new CAFE standards mandate that automakers raise the average fuel efficiency of new cars and trucks to 54.5 miles per gallon by 2025. These are lofty and commendable goals. But for engine designers and automakers, are the new standards even feasible for real-world vehicles? The EPA believes they are, and has established a new program to prove it. Continue reading
For several years, I have seen engineers working in the industry or finishing their degree in engineering that have been looking for advanced education in ANSYS.
Some of them were unable to find a course with enough specialization, without the restrictions of classroom training, or with certified content from ANSYS.
Now, the Technical University of Madrid (UPM) has responded to this request by organizing, in collaboration with ANSYS, an online master’s degree with the goal of training experts in fluid mechanics and solid mechanics numerical simulation using ANSYS engineering tools. Continue reading
I enjoy working on every article I coordinate for ANSYS Advantage magazine. I always learn something new while assisting ANSYS customers and staff tell their stories of excellence in engineering simulation. I have no favorites as I appreciate all of the articles. But, I decided to let our readers choose their top five, based on the power of downloading. The following are the most-read articles from the four issues (three regular issues and one special issue for oil and gas) of ANSYS Advantage published last year. All these stories have one thing in common: They feature robust and reliable design practices. Drumroll please …
Delamination or interlaminar fractures of composite laminates are generally caused by high interlaminar stresses that arise due to mismatch in elastic properties between plies and at free edge. Therefore, understanding the behavior of these stresses is of critical importance in the assessment of structural integrity of composite materials and structures. Continue reading
I am excited to go to Colorado at the end of May…and it is not because of what you have been reading in the news! It is because I am excited to attend the NAFEMS 2014 America’s Conference that will be held May 28th-30th in Colorado Springs, CO.
First, what is NAFEMS. NAFEMS is a non-profit that was created in 1983 in the UK by the National Engineering Laboratory. The acronym stands for “National Agency for Finite Element Methods and Standards”. But it grew from there and is now referred as the International Association of the Engineering Modelling, Analysis and Simulation Community (from nafems.org). It is a very important organization for simulation and the dynamism of the simulation industry. It provides training in simulation, helps establishing simulation best practices, is an advocate for simulation deployment, etc. Continue reading
As a Marie-Curie fellow, I have obtained my PhD degree at University College London (UCL) under the supervision of Dr Vanessa Díaz. Together with twelve other Marie-Curie fellow students, I have been a member of the European project “Medical Devices and Design in Cardiovascular application” (MeDDiCA). Located in the UK, Italy, France, the Netherlands and Romania we each conducted our research in the field of cardiovascular engineering. Continue reading
