The International Journal of Engineering Science publishes original research pertaining to the application of the physical, chemical and mathematical sciences to engineering. Emphasis is given to those contributions concerned with the cross-fertilization of these fields and research in the allied regions of mechanics, electricity and magnetism, thermodynamics, physical chemistry, both from continuum and molecular points of view. Applied research involving recent developments is welcome in such interdisciplinary areas as biomechanics, system theory, energy and approximation theory, applied and computational mathematics, as applied to basic problems in engineering science.
