Did you know that NASA has shown that 45 percent of the first-day spacecraft electronics failures were due to damage caused by vibrations during launch? That American consumers have spent over $6 billion repairing and replacing smartphones after they’ve been dropped? With the Internet of Things (IoT), electrical devices and systems must be more resilient than ever, resistant to changes in temperature, dust infiltration, electromagnetic interference, vibration, impact, and fatigue.

Determining the applicability and reliability of composite materials can be extremely complex. Engineering layered composites involves many definitions including numerous layers, materials, thicknesses and orientations to predict how well the finished product will perform under real-world working conditions. Simulation can assist you in predicting stresses and deformations as well as a range of failure criteria for composite design. ANSYS Composite PrepPost software provides all necessary functionalities for finite element analysis of layered composites. New capabilities released with ANSYS 17.0 can make to easier to effectively design composites. Continue reading
Do you routinely tackle mechanical simulations in the field of linear dynamics? Are you unhappy with your simulation times? If you answered yes to both of these questions then keep on reading. ANSYS Mechanical 17.0 has many exciting new features — far too many to cover here. This post focuses on only one of these new features: the improved performance for linear dynamics simulations in Distributed ANSYS. Continue reading
It is a great pleasure to guest blog for ANSYS again after my post in 2014 entitled Reshaping the Future of CFD Using Mesh Morphing. We continue to increase our commitment to deliver the high-performance mesh morphing technology of RBF Morph and began our new product project at the beginning of 2014.
We presented the first industrial applications at the Automotive Simulation World Congress in Tokyo in October 2014, and officially launched the RBF Morph ACT Extension on the market at the ANSYS Italian UGM in May 2015. At the end of 2015, we posted a free version (with limited functionality) in the ANSYS App Store. Continue reading
As we all know, a frequent challenge in FEM is the evaluation of stress results, in particular with cyclic stresses. The FKM guideline “Analytical Strength Assessment of Components” describes a static strength assessment as well as a fatigue strength assessment. This guideline was developed by the Advisory Board for Engineering and Research for various applications in mechanical engineering and other sectors. Continue reading
If you’ve heard anything about ANSYS 17.0, it’s that it is faster than ever. Faster solvers, faster processing, greater core counts — it all sounds great, doesn’t it? Everyone wants to get their work done faster, and faster is better than slower, isn’t it? But what exactly does “faster” mean to engineers performing structural analysis simulations today? Continue reading
Every day between now and February 7th will turn up the excitement about the biggest day of American football, the SUPER BOWL. It will take place right here in the San Francisco Bay Area. Promoters are calling Super Bowl 50 the biggest Super Bowl ever.” Starting with the Run the Road to the Super Bowl 10K, 5K Run on January 10, to the Metallica and Cage The Elephant concert the night before the big day, events will be hosted to entertain all. This makes me think of football and football concussion.
On the 18th of February, we’re hosting a webinar showcasing some exciting new methods to increase the number of ways reliable electronic systems can be designed. You can register now but first let me tell you a little about why it’s important.
The proliferation of electronics into every product arena can’t be denied. Electronics bring huge benefits in terms of features and functionality to pretty much any device. This means that electronics are being placed in more varied environments — and subjected to more demanding loads — than ever before. Continue reading
Highly non-linear simulations can be difficult to converge using the implicit simulation tools. The implicit route can involve several restarts trying different settings each time. Another methodology is available for these non-linear simulations that is explicit dynamics. Explicit dynamics can be used to simulate anything from quasi-static simulations to hypervelocity impacts.
This wire crimping analysis (shown above) is highly nonlinear with large deflections and complex contact. With explicit this is easier to set up as we can specify global contact. Continue reading
