LMS Samtech Samcef Composites
Accurately simulate the behavior of layered composite structures and their progressive degradation including delamination
The integration of LMS Samtech Samcef solvers in NX CAE opens a new range of nonlinear simulation capabilities. This new product, together with Siemens draping technology, creates an ideal integrated environment for the design of composite structures and components.
LMS Samtech Samcef Composites allows you to tackle and support various kinds of analysis including:
- Linear static, buckling and modal analysis
- Nonlinear static analysis (including postbuckling and collapse simulations)
See LMS Solver Suite for full capabilities of Samcef solvers (such as thermomechanics or nonlinear dynamics).
Combined with NX laminate composites, this composite simulation solution allows you to assign laminates (including layered, woven and sandwich materials) to models made of multilayered membrane, shell and volume elements.
With LMS Samcef Composites, you can also improve the accuracy of a lightweight structure by modeling advanced nonlinear material effects (such as progressive damage simulation, or delamination, at the interface of the plies and inside the plies leading to fiber breakage and matrix cracks). Due to the high level of expertise gained during collaborations with research centers and industries, specific material laws coupling inter and intra-laminar damages are also available.
NX CAE Environment
The NX CAE environment for the LMS Samcef solver enables engineers to build finite element models, define solution parameters and evaluate results using the LMS Samcef solver. This environment allows you to take advantage of the powerful geometry editing, meshing and general preprocessing capabilities in NX CAE to build analysis models for the LMS Samcef.
LMS Samcef Composites offers a ply-by-ply result recover for the first ply failure criteria (such as maximum stress, Tsai-Hill, Tsai-Wu, Hashin and Puck) and displays the envelope of the failure criteria (such as the critical result, ply or load case). These results are directly computed by the solver.
Progressive Damage Simulation
Based on the continuum damage mechanics:
- The progressive damage inside the ply – which accounts for fiber breakage, matrix cracking and fiber-matrix decohesion – is available.
- You can simulate the delamination studied with the cohesive elements approach.
A nonlocal model that couples the two kinds of damages allows you to be closer to the physical tests observation. Dedicated postprocessing allows you to follow progressive damages growth.
