Abaqus Composite Material Analysis Skills

Overview

This skill module provides specialized skills for Abaqus composite material analysis, including laminated plate structure analysis, failure criteria, and progressive damage simulation.

Skills List

1. Composite Laminate Analysis (skill_composite_shell)

Analyze the stiffness, strength, and failure of multi-layer composite laminates using Classical Laminate Theory (CLT).

Applicable Scenarios:

• Aircraft structures (wings, fuselage)
• Wind turbine blades
• Automotive body panels
• Marine structures

Code Snippet:

# Layup definition: (angle°, thicknessmm)
layup = [
    (0, 0.25), (45, 0.25), (-45, 0.25), (90, 0.25),
    (90, 0.25), (-45, 0.25), (45, 0.25), (0, 0.25),
]

# Orthotropic material
material.Elastic(
    type=LAMINA,
    table=((E1, E2, nu12, G12, G13, G23),)
)

# Create composite layup
compositeLayup = part.CompositeLayup(...)

for i, (angle, thickness) in enumerate(layup):
    compositeLayup.CompositePly(
        name=f'Ply-{i+1}',
        region=region,
        material='T300-5208',
        thicknessType=SPECIFY_THICKNESS,
        thickness=thickness,
        orientationType=SPECIFY_ORIENT,
        orientationValue=angle
    )

Quick Reference

Layup Angles

Angle	Direction	Application
0°	Along reference direction	Axial load bearing
90°	Perpendicular to reference direction	Transverse stiffness
±45°	Bias	Shear stiffness

Failure Criteria

Criteria	Description
Hashin	Distinguishes fiber and matrix failure
Puck	Considers angular effects
LaRC	More accurate but complex

Failure Indices

• HSNFTCRT > 1: Fiber tension failure
• HSNFCCRT > 1: Fiber compression failure
• HSNMTCRT > 1: Matrix tension failure
• HSNMCCRT > 1: Matrix compression failure
