Compressive Behavior of Luffa Sponge Material at High Strain Rate
The strain rate effect of luffa sponge material is an indispensable property for it to be used for acoustic, vibration, and impact energy absorption. Compressive tests at different strain rates on cylindrical column specimens of luffa sponge material were conducted over a wide density ranging from 24 to 64 kg/m. A photographic technique was applied to measure the section area of the specimen wi...
متن کاملHydrogen Embrittlement of Duplex Steel Tested Using Slow Strain Rate Test
P. Vaňová, J. Sojka. VŠB Technical u niversity of O strava, FMME, Ostrava, Czech Republic This paper is dealing with hydrogen embrittlement of austenitic-ferritic 2205 duplex steel using the slow strain rate test (SSRT). The original material was subjec ted to heat treatment under 700 °C during 5 hours and f ollowing aircooling with the aim of pr ovoking sigma phase pr ecipitation and embrittle...
متن کاملMaterial Properties and Constitutive Modeling of Infant Porcine Cerebellum Tissue in Tension at High Strain Rate
BACKGROUND The mechanical characterization of infant porcine cerebellum tissue in tension at high strain rate is crucial for modeling traumatic cerebellum injury, which is in turn helpful for understanding the biomechanics of such injuries suffered in traffic accidents. MATERIAL AND METHOD In this study, the infant porcine cerebellum tissue was given three loading velocities, ie, 2s-1, 20s-1 ...
متن کاملVirtual melting as a new mechanism of stress relaxation under high strain rate loading.
Generation and motion of dislocations and twinning are the main mechanisms of plastic deformation. A new mechanism of plastic deformation and stress relaxation at high strain rates (10(9)-10(12) s(-1)) is proposed, under which virtual melting occurs at temperatures much below the melting temperature. Virtual melting is predicted using a developed, advanced thermodynamic approach and confirmed b...
متن کاملHigh Strain Ra 33 . High Strain Rate and Impact Experiments
Experimental techniques for high-strain-rate measurements and for the study of impactrelated problems are described. An approach to classifying these experimental techniques is presented, and the state-of-the-art is briefly described. An in-depth description of the basis for high-strain-rate experiments is presented, with an emphasis on the development of a range of strain rates and a range of ...
