Nonlinear – Simulating Reality, Delivering Certainty

Using Global Adaptive Remeshing in Marc

Pedro Chou — Tue, 12 Jun 2018 17:25:12 +0000

During my career as a stress analyst, I have used several commercial Finite Element codes but when it comes to nonlinear analysis, Marc is the solution that really stands out. The complete element library, material models, and robust nonlinear algorithms enable Marc to solve problems from large deformations to material nonlinearity to general contact and ...

Multi-scale material modeling for additive manufacturing

Product Marketing — Mon, 01 Aug 2016 07:19:02 +0000

While additive manufacturing of reinforced polymers is appealing and increasingly considered for production of actual parts, major obstacles must be overcome by engineers. Dimensional accuracy of the part must obey to strict tolerances that may not be met due to thermally induced part distortion or poor surface roughness. On the material side, an anisotropic material behavior is brought in by the specific 3D printed layered architecture and oriented reinforcements. This process-induced material behavior make the part mechanical response challenging to predict.

Therefore, Digimat, the material modeling platform, can offer you a solution to overcome your challenges.

Manufacturing Simulation Reduces Development Costs and Time in Cold Forming Tool Design

Product Marketing — Tue, 28 Jun 2016 18:38:40 +0000

Omni-Lite Industries is an advanced material company. They recently designed a new part that was exhibiting a unique material flow. The part was cold formed out of 1100 aluminum material.

The initial tool design was completed and reviewed using the Simufact.forming simulation. Upon initial review, everything seemed to be acceptable, with the exception of the volume of material in the flange of the part. The second station trap extrusion die radius was then reduced in order to accommodate the material volume requirements.

Accurately Predicting the Behavior of Pneumatic Tires

Product Marketing — Thu, 16 Jun 2016 17:00:31 +0000

When developing the sub-systems of a vehicle, compromises have to be made among several contrasting objectives. On one hand, one wants to set all sub-systems - such as suspensions - so that they allow efficient and safe handling of the vehicle. On the other hand, comfort cannot be sacrificed too much. Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. However, it is very challenging to model them due to both their complicated composition and the materials used in their manufacturing process. On top of that, the modeling is done by suppliers and an in depth understanding of the interaction with the vehicle must be attained.

Nonlinear Analysis in MSC Nastran to Reduce Design Bottlenecks

Product Marketing — Tue, 14 Jun 2016 17:00:47 +0000

Sporadic use of advanced finite element analysis (FEA) software, such as nonlinear analysis by design engineers, can result in either excessive refresher training time or a bottleneck while in the queue for an analyst. The cause is a result of different types of solvers requiring different models. Commercially available translators can help, but still require significant amounts of cleanup. However, by integrating solvers in MSC Nastran’s SOL 600, the same model in the familiar MSC Nastran format can be used for both liner and MSC Marc nonlinear analysis.

Case Study: Predicting Virtual Allowables

Product Marketing — Thu, 12 May 2016 20:00:34 +0000

During the process of designing lightweight CFRP structures, one usually needs access to allowable values. However, allowables generation is particularly costly and time-consuming. Each characterized material system must cover various layups, coupon tests, and environment conditions. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property. With advanced ...

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 ...
