Multi-scale material modeling for additive manufacturing

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.

Optimum Design of a Steel Connection of a Glass Façade for a High Rise Building

The use of glass in the exterior facades provides more light and good ambience to the inhabitants of a building. In our case, this leads to a high increase of the use of glass in the facades. The curtain wall is formed by an aluminum framework with steel connections. These steel connections are welded to the building while steel beams and bolted to the aluminum frame.

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 ...

Piezoelectric Simulations With Marc

Piezoelectric sensor-actuator technology is often used in high-tech industries like medical, mechanical, automotive engineering and semiconductor markets. Applications of piezo-based ultrasonic sensors range from fuel injectors, flow-rate metering, ultrasonic welding, and high-resolution material testing to medical diagnostics. A piezoelectric finite element analysis involves computation of coupled stress and electric field in certain crystalline materials. In ...

Multi-Scale Simulations With Marc and Digimat

Composite materials of various types (unidirectional composites, short fiber reinforced plastics, nano-composites, ceramics, etc.) exhibit highly nonlinear, anisotropic, strain-rate and temperature dependent properties in mechanical, thermal and electrical fields. They often exhibit enhanced performance with respect to density as compared to traditional structural materials. However, simulating composite structures is complicated, and usually requires a micro-mechanical, ...

Marc Simulates Welding of Nuclear Pressure Vessel Reactor Nozzles

The reactor pressure vessels make up the heart of a nuclear power plant, containing the core, core shroud and coolant. These nuclear plants were built and started operating 20 to 30 years ago. The company operating this plants needed to know how this welds can be expected to perform after a long period of service. ...
