Are Alternative Facts acceptable to an Engineer?

Posted by Geoff Haines on 26-Jan-2017 13:29:03

We are currently in a place called “post-truth era” where “alternative facts” are being positioned as acceptable currency. I was wondering how this impacts an engineer who must work with the laws of nature and harness them for the good of mankind.

A key lesson we all learn during our engineering education and working experiences is that the mechanical psychical world obeys Newtons Three Laws of Motion.

These laws have the laid the foundation for classical mechanics upon which engineers have built the knowledge and hence technology that has delivered cars, aeroplanes and got mankind to the moon.

Delamination Modelling

Posted by Andy Woodward on 20-Jan-2017 09:00:00

Delamination is one of the critical failure criteria in the design of laminates and any bonded joint. Modelling it with simulation software is possible, but can be very fiddly and labour intensive in many finite element codes.  It is often necessary to pre-determine where delamination will occur and then create interface elements that capture the cohesive behaviour of bond.  Doing this manually within a GUI environment is not fun.

The Marc finite element solver, from MSC Software, makes this very easy by having the solver detect where delamination is likely to occur between unique materials (or within a homogenous material) and then create the interface elements itself.  This represents a massive saving in time for the FEA engineer creating these type of models.

The threat of 3D Printing to intellectual property

Posted by Geoff Haines on 23-Jun-2016 15:00:00

Additive manufacturing, commonly referred to as 3D printing, is widely recognised as a leap forward in the manufacturing of a wide variety of products. From prosthetic limbs to smartphone cases, 3D printing represents an opportunity to solve a wide range of manufacturing challenges across industry sectors. 

Still, while 3D printing has been lauded for its ability to produce customized parts at a significantly faster rate than standard manufacturing practices, it’s not without its risks.

The advantages and disadvantages of self-driving cars

Posted by Geoff Haines on 02-Jun-2016 21:00:00

The automotive sector is one area where technology is developing at a significantly fast pace. From developments in green technology to forward emergency braking in luxury vehicles, innovation is at the heart of the automotive sector. 

A particularly popular area of interest is driverless vehicles. Essentially, these self-driving cars use a vast array of sensors to understand the environment around the vehicle and use this information to navigate through the streets to your destination – without the need for assistance from a human.

3 things you need to know about Stage V emissions standards

Posted by Geoff Haines on 19-May-2016 18:00:00

Developing a new engine is complicated enough without having to deal with meeting regulations for carbon emissions. For many businesses, it’s going to get tougher. 

As the European Commission continue to clamp down on environmentally unfriendly technologies, many organisations producing engines for new non-road vehicles will face new challenges with the introduction of Stage V emissions standards in 2019-2020.
