Frontiers in Applied Mechanics is a compilation of cutting-edge research in applied mechanics by 65 of the world's leading researchers and academics. It comprises current new research directions and topics in the field, as well as developments in the classical branches of applied mechanics; namely solid mechanics, fluid mechanics, thermodynamics, and materials science. Frontiers in Applied Mechanics also includes contributions from new emerging areas such as nanomechanics, biomechanics, electromechanics, the mechanical behavior of advanced materials, mechanics of soft materials, and many other inter-disciplinary research areas in which the concepts of applied mechanics are extensively applied and developed. The mathematical modeling and methodology for applied mechanics are also included, with applications to many interesting mechanics aspects. All articles were carefully selected following a thorough review process by peers. The aim of this collection is to contribute to knowledge in all aspects of applied mechanics; to improve the reader's understanding of the topics and aid their corresponding advances in the field. Readers may also use the contents as a guide for future research directions.
