... to insert due to buckling against the thin but hard-to-penetrate brain meninges. To address such implantation challenges without introducing further damage to the brain, this paper presents our design and prototype of an inchworm-type insertion device that conducts a grip-feed-release incremental motion...

...James Magargee; Jian Cao; Rui Zhou; Morgan McHugh; Damon Brink; Fabrice Morestin The cyclic and compressive mechanical behavior of ultrathin sheet metals was experimentally investigated. A novel transparent wedge device was designed and fabricated to prevent the buckling of thin sheets under...

... sets for two axisymmetric parts were designed and tube hydroforming experiments were carried out on SS 304 tubing. Through this methodology, an expansion rate of 71% was achieved. 19 04 2011 18 08 2011 09 12 2011 09 12 2011 bifurcation buckling design engineering...

.... In this paper, a mechanics of materials description of the creping process is presented. Based upon previous experimental observations, the mechanism of this creping process is proposed as a periodic debonding with a strength-of-materials failure criterion applied and buckling sequence of an elastic thin film...

... applications for nerve repair and regeneration. For better nerve regeneration performance, the HFM groove geometry should be carefully controlled. Towards this goal, in this study the polyacrylonitrile (PAN) HFM groove number has been modeled based on the radially inward pressure-induced buckling mechanism...

... such as buckling and distortion in tube bending. This paper investigates the effects for various laser beam geometries on laser tube bending. Finite element modeling has been used for the study of the process with some results also validated by experiments. Namba , Y. , 1985 , “ Laser Forming in Space...

...L. Zhang; P. Michaleris; P. Marugabandhu Large and complex structures such as ship panels generally have various types of welding-induced distortions including angular deformation, longitudinal bending, and buckling. Developing efficient methodologies for modeling welding distortions and residual...

... the roll can be sufficiently high to cause local or gross buckling defects to form. For instance, the cylindrical core onto which the web is wound can collapse, a failure mode that is termed “v-buckling.” In other cases, while the core might remain intact, a group of layers interior to the roll can wrinkle...

... Registration (TEER) technique has been developed for precision aligning large numbers of laminae in diffusion-bonding processes based on the differential thermal expansion between the laminae and bonding fixture. However, fixture tolerances necessary to promote buckle-free TEER bonding have been found...

...P. M. Lin, Student Mem. ASME; J. A. Wickert, Fellow ASME The elastic stability of a wound coil comprising a central core and many layers of sheet metal is modeled and analyzed. A common failure mode resulting from unfavorable internal stresses—called v-buckling—is characterized by a section...

.... A curved sheet model is established to obtain the critical buckling stress in terms of stress state, geometry properties and material properties. The predictions of wave number agree well with the experimental results. The results indicate that the sensitivity of wave number on the plan view radius (PVR...
