One of the major tasks of rheology is to establish by measurement the relationships between strains (or rates of strain) and stresses, although a number of theoretical developments (such as assuring frame invariants) are also required before using the empirical data. Meer weergeven Rheology is the study of the flow of matter, primarily in a fluid (liquid or gas) state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response … Meer weergeven In practice, rheology is principally concerned with extending continuum mechanics to characterize the flow of materials that exhibit a combination of elastic Meer weergeven Deborah number On one end of the spectrum we have an inviscid or a simple Newtonian fluid and on the other … Meer weergeven Rheology has applications in materials science, engineering, geophysics, physiology, human biology and pharmaceutics.
