MaterialCenter is a Materials Lifecycle Management System designed to link material specialists to mechanical simulation. MaterialCenter captures data from integrated processes to ensure full traceability across the enterprise and throughout the product lifecycle. It addresses unique process and data requirements and drives product innovation in complex materials such as alloys, elastomers, plastics, composites, and many more. MaterialCenter

works directly with many commercial CAE products and delivers on-demand commercial Databanks to engineers across the industry.

e-Xstream also provides engineering consulting services to address any needs in accurately predicting the micro-mechanical behavior of composite materials and parts.

TECHNICAL MEANS

Digimat allows:

• Material engineering: through the micromechanical modelling approach to predict the nonlinear, anisotropic, rate-dependent behavior of complex multi-phase composite materials

Structural engineering: through the coupling of Digimat material models with commercial CAE codes to accurately predict the behavior of composite structures taking into account the influence of process simulation

• Process Simulation: Digimat provides process simulation solutions for the additive manufacturing of polymers. It helps process engineers to anticipate manufacturing issues and optimize part quality by predicting the relative influence of the various process parameters.

Digimat is used to study the thermo-mechanical behaviour of material lab

samples and predict the influence of the material microstructure on the

product end-performances. Through partnerships with the aerospace

sector, e-Xstream has developed the appropriate tools and extensive

know-how for modelling materials typically involved in lightweight

aerospace composite structures.

Material Center allows:

• Dashboards for quick evaluation of materials data management projects and management oversight.

• Work request and approval workflow to keep projects on track.

• All materials-related processes, input and output documented through Audit Trail.

• Process-oriented, automation approach to data management.

• Robust and intuitive interface for data search, retrieval and comparison for all data types – tabular, curves, images, etc.

• Web-based interface to data management processes that enable distributed data authoring and maintenance.

• Built-in job queue interface that optimizes execution of materials simulation processes.

• Proven scalability to 100,000s of processes and petabytes of data to meet the needs of engineers for years to come.

• Integrates commercial Databanks for accessing critical materials data.
