Uniaxial & multi-axial loading

• Tension / compression (quasi-static to controlled-rate loading)

• In-plane shear, shear–compression interaction, and combined loading

• Biaxial / shear-biaxial concepts where loading paths matter

Damage & failure under realistic constraints

• Notch sensitivity, bearing / bypass, and local stress concentrators

• Progressive damage behavior and stability of failure modes

Bonding & interfaces (critical for hybrid structures)

• Lap / double-lap style joint testing concepts

• Interface-driven failure: adhesive, cohesive, interlaminar, and mixed failure modes

Fracture & mixed-mode concepts

• Mode I / Mode II / mixed-mode approaches (selected based on design needs)

• Crack initiation vs growth, and energy-based interpretation

Translate design questions into a test matrix (variables, bounds, acceptance criteria)

Align methods to relevant standards where appropriate (or document deviations clearly)

Build/modify fixtures for alignment, constraint control, and repeatable boundary conditions

Cryogenic readiness: thermal conditioning plan, hold-time strategy, instrumentation survivability

Deliver design-usable outputs: stress–strain curves, stiffness, strength, failure envelopes, and uncertainty
