Finite Element Analysis Services

As a business professional or entrepreneur, you should demand engineering solutions that tackle the toughest challenges. Proof Engineering’s team delivers just that - affordable, high quality Finite Element modeling and simulation and virtual prototyping based designs that address all of your requirements. From simple linear static analyses to car crashes and human body responses, our engineers can assist you in understanding and solving complicated technical problems. Lending to this success, we use state-of-the-art industry tools such as NE Nastran, Femap and LS-Dyna to obtain accurate solutions for the most demanding applications.
Capabilities
Proof Engineering specializes in Finite Element Analysis to accurately predict the performance of products and processes. We effectively solve structural, thermal, fluid and multi-disciplinary engineering problems through state-of-the-art technologies reinforced by years of experience. These tools are applicable to real world problems in a variety of industries.

Why use Finite Element Analysis?
Engineering practitioners today know that there are only two drivers in design/development decision making - quality and cost. Finite element analysis enables the creation of better designs by identifying failure modes early on, reducing the cost of the prototype and helping to avoid warranty costs down the road. Likewise, finite element based optimization is a powerful tool to reduce weight and material. Finite element techniques can be used to dial-in manufacturing processes, sometimes dramatically cutting lead time and cap-ex costs. Fatigue and durability estimates based on FEA results can be a fundamental decision driver for any company developing new products. And in some cases, a finite element analysis study is sufficient to meet government regulations.

Why use an Outside Company for Finite Element Analysis?
There are two considerations. If your company requires finite element analysis occasionally, then you will be avoiding the considerable expense of purchasing the software and of hiring qualified personnel to do the work. The second consideration applies when you need to perform a study beyond your engineering expertise. An experienced analyst can be crucial in helping you to get useful results, and more so if you're entering a new engineering field or working with an unusual application.
Why Partner with Proof Engineering for FEA?
One important benefit in partnering with Proof Engineering is our ability to adapt solutions to a particular industry. Because of exposure and experience in many industries, we can select the most effective and practical tool to suit the task at hand, thus saving our clients time and money. For example, if a project is a structure that requires a building permit, we will use a beam modeler that will perform all necessary building code checks and generate reports in a reviewer friendly format. Or, if our client designs equipment for the Navy and requires a Dynamic Design Analysis Method, we will use Nastran for this work because it will most likely be the end customer’s expectation. A second advantage is the flexibility of our modeling approaches - we can construct a complicated multiple physics system model with thermal, fluid and structural interactions, or we can (not always) simplify complex physics with a few assumptions and a hand calculation, to end up with a small static model on a component level. Our philosophy is to keep things as simple as possible, with engineering effort adapted to project budgets and objectives. Thirdly, we understand, or in very specialized cases, develop an in-depth understanding of processes behind the projects that we take on. This makes any product change recommendations based on analysis results easily implementable. For instance, an injection molded part will remain moldable or precision tolerances will not be specified if not warranted by functional requirements. And finally, we like to believe that we understand the physics behind the problem at hand. We routinely perform hand calculations and checks to verify that our results are reasonable and accurate. Because of this process we've been fortunate to observe time after time our clients' validation test data to agree with our analyses predictions.

Client Testimonials

ViaSol Energy Solutions CEO:

 

We’ve been working with the principals of Proof since our company was started.  The Proof team performs so well that we have incorporated their mechanical engineering expertise into our own value proposition. After completing five complex solar projects together, and helping us develop two entire product lines, we cannot imagine working with anyone else.
