Dynamic tensile testing of ligaments from the human cervical spine
This study focuses on establishing appropriate experimental methodology to facilitate investigation of the dynamic stress-strain characteristics of soft bio-tissues. Dynamic mechanical tests were conducted on ligaments from the human cervical spine (neck), using a tensile split Hopkinson bar device. The strain rates imposed were of the order of 10~10/s. As ligaments are extremely soft and exten...
متن کاملExperimental Study on Tensile Properties of a Novel Porous Metal Fiber/Powder Sintered Composite Sheet
A novel porous metal fiber/powder sintered composite sheet (PMFPSCS) is developed by sintering a mixture of a porous metal fiber sintered sheet (PMFSS) and copper powders with particles of a spherical shape. The characteristics of the PMFPSCS including its microstructure, sintering density and porosity are investigated. A uniaxial tensile test is carried out to study the tensile behaviors of th...
متن کاملDynamic tensile test and specimen design of auto-body steel sheet at the intermediate strain rate
In this paper, the tensile testing method at the intermediate strain rate is established and tensile tests of steel sheets for an auto-body have been performed to evaluate dynamic material properties. A high speed tensile testing machine has been developed for tensile tests at the intermediate strain rate. A simple jig fixture for gripping a specimen has been designed to diminish the load ringi...
متن کاملdynamic coloring of graph
در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
15 صفحه اولModelling of Tensile Behaviour of Sheet Moulding Compounds
An original approach to compute the longitudinal tensile break stress of multiphase composite materials with short fibers reinforcement is presented. The most obvious mechanical model which reflects a multiphase composite material is a pre-impregnated material, known as prepreg. We may include in this class of prepregs, Sheet-and Bulk Moulding Compounds. The model is seen as consisting of three...
