Altair Multiscale Designer for Unidirectional (UD) Composites

Test ID



Tensile tests per ASTM D3039 are performed on specimens cut from a [0], [90], [90/0], and [45/-45] laminates. Compression tests per ASTM D6641 are performed on specimens cut from a [0], [90], and [90/0] laminates. Data in the form of stress-strain curves paired with DIC images is converted into an Altair Multiscale Designer material model for import into CAE software (Altair OptiStruct, Atair Radioss, Abaqus, or LS-Dyna).

Included Tests

4x M-204 Tensile Stress-Strain, Strength, and Modulus
3x M-209 Combined Loading Compression (CLC)


Testing can be performed at room temperature dry (RTD), cold temperature dry (CTD), and/or elevated temperature wet (ETW) conditions. Quoted prices are for RTD; CTD and ETW conditions incur an additional charge. If interested in adhering to CHM-17 b18 standards, three (3) separate batches of material must be tested.


: 50 tensile bars


: 30 compression bars

This TestPak produces a MDS material model file for UD composite materials. This material model can be used in structural simulations within a variety of commercial finite element solvers, including Altair OptiStruct, Altair Radioss, Abaqus, and LS-Dyna to more accurately simulate composite material behavior. The Altair Multiscale Designer software is accessed using HyperWorks Units (HWUs).
