The Rise of Additive Manufacturing

When early manufacturing giants realized that their mass production techniques would not be effective if they wished to maintain their competitive edge, they started to research new manufacturing methods. One of the most remarkable outcomes of these efforts was rapid prototyping. In the past, production had always been a way to convert or shape a …

Room to Room Vibration Tranmission

Architects and acoustic consultants struggle to accurately estimate the vibration reduction index for their building designs. ISO 10848 defines a method for measuring this, but it is a long, tedious and expensive process which is implemented by building two rooms and their junctions one by one, exciting the wall and measuring the flanking and direct noise. This process must be done for each building design. When the design changes or the desired results are not achieved, the structure must be demolished and built again from the beginning.

Global Adaptive Meshing In Marc

Adaptive meshing is a simulation technique used to automatically remesh parts of a finite element model during the solution phase, based on certain criteria set at the start of the analysis. Adaptive meshing can be broadly classified into two types – global remeshing and local adaptivity. Global adaptive meshing is extremely useful for cases where …

Value of Simulation to Material Testing and Development

This article was originally posted by Bob Schmitz, Senior Business Development Manager for e-Xstream engineering on Composites World magazine. Traditionally we have designed, characterized new materials with physical testing by using simple coupon tests, which are affordable and the results have generally been accepted as fact, even if the sample size is small. However, material science has …

Simulating Brake Squeal Noise

Brake squeal is one of the most challenging problems that car manufacturers have today. It occurs as a result of the vibration of the brake components such as brake disc and brake pads and therefore it disturbs the driver and passengers. Furthermore, because of its complex nature it is hard to completely understand the causes …

Multidisciplinary Solutions For Brake Squeal

Although engineers have started to use simulation software to test brake squeal, its complex nature usually requires more than one different software and discipline. This makes it difficult to transfer data from one software to another and to work in different environments. To address complex brake squeal in one environment, multidisciplinary solutions (MD) can be used. …
