| In the field of aircraft structures the
main thrust in the R&D effort during the past three decades has been on the development
of understanding of static and dynamic behavior, in the development of software
packages and development and application of testing techniques. An important part
of this effort has been oriented towards application to composite structures,
a significant development of which has been a state of art computer controlled
autoclave facility developed at NAL. Another major area of R&D effort has been
fatigue and fracture mechanics of metallic structures, which has finally resulted
in the development of full-scale fatigue test facility at NAL for fighter aircraft.
Besides this, the other fields, which had received attention, are non-destructive
testing, vibrations, stress analysis, aero elasticity, computer aided design,
experimental stress analysis, finite element method etc. |
