Dem Dry Bones Can Be Painful

By Tim

As kids, I am sure many of us were encouraged to sing the old spiritual tune “Dem Dry Bones.” The song was not only supposed to be fun, it’s educational. Remember…
The toe bone’s connected to the heel bone,
The heel bone’s connected to the foot bone,
The foot bone’s connected to the leg bone…
 

Bioengineering researchers must have taken the song to heart, because they want to know how all 206 adult human bones are connected, how they help us move; how they protect our organs, how they break, and thankfully, how they can be healed. The research studies being conducted, with the help of Abaqus FEA, are complex and extensive. They are also vitally important in helping to discover innovative treatments for ailing bones.

Researchers at the Harvard Medical School joined with engineers from Foster-Miller, Inc, to study the load bearing capacity of the spine subjected to vertebrae fractures caused by metastasis. Their study combines MRI results with Abaqus FEA to evaluate the fracture and failure processes caused by tumors in the spine. The goal is to leverage their research  to guide clinical decisions related to surgery and patient care.  You can also view a poster on their study at the SIMULIA academic web page.

According to the Podiatry Channel website  The foot and ankle contain 26 bones, 33 joints; more than 100 muscles, tendons. I can see why bioengineers are intrigued by the challenge of understanding out how this complex system functions.  The paper from the Hong Kong Polytechnic University describes the highly detailed Abaqus FEA models that they created to gain a better understanding of how to protect our feet and ankles from injury.

A group of undergraduate engineering students at Cedarville University used Abaqus to model the push-out load between a hip prosthesis stem and bone during a senior design project. Their paper outlines how the analysis results, when used along with a device that maps out the geometry of the femoral intramedullary canal, could aid orthopedic surgeons in  prosthesis size selection during hip replacement surgery.

Researchers at the Cleveland Clinic are also using Abaqus to analyze feet. They are assessing the risk of foot ulcerations in patients with diabetic neuropathy. In their study, they analyzed how bone position effects plantar pressure distribution which be used to guide the design of therapeutic footwear. 

I continue to be amazed at how researchers and medical companies are using Abaqus to analyze every part of the human body and discover innovative treatments to improve our health care. 

Feel free to share your thoughts on Life Sciences with me. I plan to tackle other industry topics in coming posts.

Enjoy,

Ohio Drivers May Paint Local Bridge FEA Red

By Kate


Hi everyone,

First, welcome back from your summer adventures! I’m surfacing after some time away and getting back into the ‘back-to school’ swing. This weekend I was catching up on some emails and came across an article that tickled my fancy. Impassioned Ohio drivers getting worked up about a local bridge on the verge of collapsing.

Looking at the ensemble of article + 19 comments, it seems that the bridge shows signs of degradation, yet the state transportation department has been pouring resources into the construction of new roads.

Until the 3D FEA analysis software was tapped.

Abaqus FEA software, also used for complex engineering, innovations in diapers and even the study of bed sores, has helped the ODOT scientifically conclude that indeed the bridge is on the verge of failure. So rather than enhancing the existing structure as originally planned, they’ve determined it’s more life-and-cost-efficient to eliminate the current bridge and start anew.

“No duh” say some of the local citizens, and they’re pushing hard for construction action now, rather than waiting until 2014.

One of the commenters suggests they literally paint the FEA analysis onto the bridge to show exactly where the red-zone’s located (red being the crumble danger zone), hopefully garnering immediate action. ;-)

And there was even someone that shared wish lists of color schemes and aesthetics for the new bridge.

Which got me to thinking: Ohio, why not go further than the FEA analysis?

You can share a 3D model of the new bridge design and have citizens vote online for their preferred colors, surrounding vegetation, etc.

You’re lucky to have active citizens who care about the bridge; get them involved in the project with other flavors of the same 3D software that helped you confirm your action plan.

Now that’s democratic !

Best,
Kate

Why We Shouldn’t Be Conservative with Energy

The Energy & Process industry has traditionally been conservative in adopting new technologies. But at a time when many are grasping onto conservative business decisions to ride through the economic crisis, it’s time for Energy & Process to get more radical.

As new build and maintenance/refurbishment projects reach high complexity levels, we need a fresh look at how processes are accomplished and what new technologies have to offer.

Let’s get innovative . . . by looking at the shipbuilding and aerospace industries, for example. How are these sectors working to complete projects on time and within budget?

Part of their ‘secret’ is employing 3D virtual planning software. An example of this technology is Dassault Systèmes’ DELMIA, which allows companies to plan, visualize, and validate the schedule of any capital project. This allows companies to minimize project delays by optimizing the schedule, and ensuring the health and safety of the workers.

Though this technology has been successful for many years in other industries, it’s comparatively new to the Energy industry. DELMIA has perfected the technology with years of development and implementation experiences and has been successful in innovatively applying the solution to the Energy & Process industry.

When we first present our solution to prospective customers, however, some have doubts on whether our technology can do the job. We are always pleased to see when the customers show tremendous faith and confidence in our solution as the project progresses and results become available. And what speaks better than actual results?

The savings to the projects have been millions of dollars with a return on investment (ROI) of up to 20-to-1. Check out some of these examples here.

The Energy and Infrastructure industries are leading the pack in the economic recovery and growth efforts in most countries around the world and are all set to emerge with advantage when the crisis tides over.

It’s an exciting time for all of us as new and innovative technologies are making their way to this traditionally conservative field.

As of today, the Energy & Process Industry is on the upswing in adapting new technology.

But are they moving fast enough?

Best,

Karun
