Foreword
ItiswithdeepsatisfactionthatIwritethisforewordtotheProceedingsoftheSixth
NationalSymposiumonRotorDynamics(NSRD-2019)heldduring2–3July,2019
at CSIR-National Aerospace Laboratories, Bengaluru, India. Rotor dynamics is a
keyandchallengingaspectofengineering applications involving machinerieswith
rotating parts.Theprominentresearchers inthefieldofrotordynamics andrelated
areas from India regularly organize this symposium, biennially. It was a great
pleasure to host the Sixth National Symposium fully dedicated on this subject, at
CSIR-NAL, Bengaluru.
I feel proud to state that there has been overwhelming response from students,
researchscholars,academicians,scientistsandIndustryfromalloverthecountryin
the form of research papers to this conference. The invited lectures given by
eminentpersons with decades of rich experience providedvaluable insights on the
