For realizing the intelligent vehicle suspension design with magneto-rheological (MR) fluids dampers, extensive laboratory measurements are performed to characterize the symmetric and asymmetric hysteresis force properties of a MR-damper, under a wide range of drive current and harmonic excitation conditions (frequency and stroke). The proposed asymmetric damping force generation (ADFG) algorit...

Plants gums are complex mixtures of different polysaccharides with a variety of biological activities and pharmaceutical applications. Few studies have focused on physicochemical and biological properties of gums obtained from different plants. This study was designed to determine potential pharmaceutical and pharmacological values of the gum exudates and its isolated biopolymers obtained from ...

Images of tumor mechanical properties provide important insights into malignant-cell processes manifest by extracellular matrix (ECM) stiffening and remodeling. This article presents a pilot study measuring in vivo mechanical-property characteristics of rodent mammary tumors using an ultrasonic shear-wave imaging technique. Shear waves are generated by a needle inserted into the tumor of anesth...

The capability of processing robust Engineered Cementitious Composites (ECC) materials with consistent mechanical properties is crucial for gaining acceptance of this new construction material in various structural applications. ECC’s tensile strainhardening behavior and magnitude of tensile strain capacity are closely associated with fiber dispersion uniformity, which determines the fiber brid...

An engineered cementitious composite (ECC) suitable for wet-mixture shotcreting (sprayable ECC) in the fresh state, while maintaining tensile strain-hardening behavior in the hardened state, has been developed by employing a parallel control of micro-mechanics-and rheology-based design. In the development concept of sprayable ECC, micromechanics is adopted to properly select the matrix, fiber, ...
