Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is ...

PURPOSE The design of the attachment must provide an optimum stress distribution around the implant. In this study, for implant overdentures with a bar/clip attachment or a locator attachment, the stress transmitted to the implant in accordance with the change in the denture base length and the vertical pressure was measured and analyzed. MATERIALS AND METHODS Test model was created with epox...

Infallible creep rupture life prediction of high temperature steel needs long hours robust testing over a domain stress and temperature. A substantial amount effort has been made to develop alternative methods reduce the time cost testing. This study presents finite element analysis coupled with ductility based damage model predict under influence multiaxial state ex-service as-received Grade 9...

The design of adhesively bonded connections for structural applications has recently become a major field research, with extensive in the automotive and aerospace industries. In these structures, joints are often subjected to important static dynamic loads, which require careful geometrical dimensioning material selection. performance analysis adhesive under conditions is made numerical modelin...

Slow, intermediate and high strain rate experiments with UT geometries are performed on aluminum AA7075-T6 sheet metal at various temperatures. The comprehensive experimental program characterizes the plasticity response temperatures ranging from 20°C to 360°C rates 0.001/s 150/s. elevated temperature - a hydraulic tensile testing machine Split Hopkinson Pressure Bar system Load Inversion Devic...

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...
