Rheology

Rheology is the study of the flow and deformation of materials under applied forces. It focuses on materials that do not behave as ideal solids or Newtonian fluids, such as polymers, gels, suspensions, and biological fluids. Rheology examines properties like viscosity, elasticity, and viscoelasticity to understand time-dependent material response. This field is essential in industries including food processing, pharmaceuticals, cosmetics, polymers, and biomedical engineering. Rheological behavior influences manufacturing, product stability, and performance. By analyzing stress–strain relationships and flow characteristics, rheology helps optimize material design and processing conditions. It also plays a role in understanding biological systems such as blood flow and tissue mechanics. Rheology bridges fluid mechanics and solid mechanics, providing a unified framework for complex material behavior.
