This book focuses on the qualitative theory in structural mechanics, an
area that remains underdeveloped. The qualitative theory mainly deals
with the static deformation and vibrational modes of linear elastic
structures, and cover subjects such as qualitative properties and the
existence of solutions.
Qualitative properties belong to one type of structure, are at the
system level and of clear regularity, and often result from analytical
derivation and logical reasoning. As for the existence of solutions, it
addresses a fundamental issue in structural mechanics, and has
far-reaching implications for engineering applications.
A better understanding of qualitative properties can assist in both
numerical computation and experimental studies. It also promotes the
development of better dynamic designs for structures. At the same time,
a sound grasp of the existence of solutions and related subjects can aid
in quantitative analysis, and help researchers establish the theoretical
background essential to their work.
This book is among the few that is dedicated exclusively to the
qualitative theory in structural mechanics and systematically introduces
the important and challenging area to a wide audience, including
graduate students in engineering.
