- Digital aerodynamic Stiffness Tester, the bending cycle based on ASTM test method to detect fabric softness.
- Based on the results and finite element formulation, the flutter force has been considered as equivalent aerodynamic stiffness matrix and equivalent aerodynamic damping matrix.
- Put forward a new method for long-span bridge buffeting analysis which using quasi-steady aerodynamic stiffness and unsteady aerodynamic damping based directly on wind tunnel test.
- The thought of my exams next week scares me stiff.
- The soldier stood stiff as a ramrod.
- An extremely stiff, erect posture.
