Our Capabilities: Nonlinear Finite Element Analysis

Sigma has recently added Nonlinear FEA to its suite of advanced engineering tools.

This new offering will allow Sigma’s engineers and designers to better tackle some of the toughest challenges by more accurately simulating nonlinear behavior, including plastics analysis, large deformation and nonlinear/time-based loading. Of particular interest is the team’s ability to effectively load and unload a part, thereby predicting any permanent deformation that may occur.

Recent clients have sent preliminary plastic models for review, enabling quick review of proposed design changes and their effects on part integrity, before more expensive prototypes and tooling are manufactured. Additionally, models were simulated at elevated temperatures to recreate the real-world testing scenarios the part was designed to withstand.

Nonlinear FEA is another tool in Sigma Design’s advanced engineering toolbox, and complements the years of plastic part experience held by Sigma’s design and engineering team.

SIGMA Design Company- Turning Smart Ideas into Product Solutions with Nonlinear Finite Element Analysis

SIGMA featured on Food Network television show Invention Hunters

In May, Sigma Design Company was featured on the Food Network show Invention Hunters. The show follows Patrick Raymond and Steve Greenberg who visit inventors across the nation hoping to find the next “million dollar idea.” Once convinced, Raymond and Greenberg bring the inventors to New York City to pitch their ideas to Lifetime Brands, Inc., one of the largest housewares manufacturers in the world.

Sigma Design Company, in collaboration with Gordon Perry Design, were recruited in March to design and create an improved working prototype for the “Pure Sure,” a valve for carton beverages, which allows children to pour a drink themselves without making a mess.

The television crew gets ready to film at Sigma’s new innovation center in Middlesex.

With only two weeks to complete the task, Sigma Senior Design Engineer Bob Messinger turned up the heat to ‘plate up a winner.’ A visit to Sigma Design Company’s new innovation center in Middlesex, NJ was all it took to convince the scouts that the new and improved product was ready for round one.

Sigma President Jerry Lynch and Gordon Perry talk with the Invention Hunters crew.

Sigma Design co-owners Jerry Lynch and Debbie Lynch, who heads a Culinary Arts Program at Middlesex County College, were excited to be a part of this show. A food-related invention was a perfect match for the team at Sigma Design Company, which can work with inventors from concept to market.
