Predictive theories of phenomena involving phase change with applications in engineering are
investigated in this volume e.g. solid-liquid phase change volume and surface damage and
phase change involving temperature discontinuities. Many other phase change phenomena such as
solid-solid phase change in shape memory alloys and vapor-liquid phase change are also
explored. Modeling is based on continuum thermo-mechanics. This involves a renewed principle of
virtual power introducing the power of the microscopic motions responsible for phase change.
This improvement yields a new equation of motion related to microscopic motions beyond the
classical equation of motion for macroscopic motions. The new theory sensibly improves the
phase change modeling. For example when warm rain falls on frozen soil the dangerous black
ice phenomenon can be comprehensively predicted. In addition novel equations predict the
evolution of clouds which are themselves a mixture of air liquid water and vapor.
