The characteristics of nonlinearity

All physical processes are to some degree nonlinear – every day, the materials that surround us all exhibit either large deformations or inelastic material behavior. For example, pressing an expanded balloon to create a dimple (the stiffness progressively increases, that is the rate of deflection decreases the more squeezing force is applied), or flexing a …

Identifying and addressing vibration issues early in the design process

A universal problem when optimizing noise and vibration is that it often conflicts with durability or cost. Multi-body dynamics helps balance these competing requirements early in the design process by addressing key vibration issues facing engineers, such as “will excitations in one part of the systems interaction with another part of the system?” MBD makes …

Assembly Modeling of Aerospace Structures Using Contact Simulation

Bolted or riveted airframe assemblies are typically modeled as continuous meshes. But advances in meshing and solver technology are changing the way we model these assembly structures. Today, continuous meshes are often replaced by individually meshed parts joined together by some type of connector or interaction definition. These individually meshed parts are typically joined together …

Consistent Management of the Model Build Process

As simulation becomes more embedded in the overall product development process, it becomes important to establish a consistent model build process. An organization can be confident in using simulation results throughout the development lifecycle only if a mature and consistent process is implemented to create the simulation models. The objective of a consistent model build …

Tackling Acoustic Challenges and Standards

Tough new noise standards, increasing pressure to innovate, and the expectation for shorter time to market without compromising quality and affordability are just a few of the challenges that acoustic engineers from every industry are facing today. Automotive engineers are faced with the demand from consumers to create lightweight vehicles, which creates obstacles for controlling …

Computer based modeling and analysis plays a pivotal role in the packaging industry as it seeks to differentiate and deliver unique value to its customers

Simulation and analysis, or Computer Aided Engineering (CAE), enables engineers and organizations to analyze and explore new packaging processes and methods in a virtual environment, reducing the time and cost requirements associated with physical and experimental testing. For over 40 years, product manufacturers in transportation industries have relied on computer simulations as a means to …
