Penetration of plastic

Abstract This paper considers the problem of non-steady penetration of a rigid projectile into an elastic-plastic target of finite thickness. The alternative is probably quartz glass, but the advantage of acrylic or Plexiglas is that it is easier to work with. What do you think about Springer Nature and its family of journals? Hello I'm a beginner in Abaqus. Judgment formula of contact state was fixed by introducing the corrected coefficient k. Fretting rate is affected by rod motion, and the presence of edges at the point of contact between rod and support accelerates fretting wear.

Long wave ultraviolet light to nanometers , which most of us recognize as "black light" the light that is often used to make decorations glow in discos and theatrical productions. However, if the stent gets stuck in the bowel then it should be removed; endoscopic retrieval is often possible and surgical intervention is rarely necessary[ 9 , 10 ]. Fatigue Standards and Fracture Standards. Standard Specification for Polyethylene Film and Sheeting.

Randomised trial of endoscopic stenting versus surgical bypass in malignant low bileduct obstruction. Can Assoc Radiol J. Intestinal perforation can occur during the initial insertion or endoscopic or percutaneous manipulation, or as a late consequence of stent placement. Standard Practice for Dissolving Polymer Materials.

The effects of the free front and rear surfaces of the target which is presumed not to be too thin and the separation of the target material from the projectile are modeled approximately, and the force applied to the projectile is calculated analytically. The hollow degree does not influence the size of stick zone but controls the position of the junction point of slip-open. Hua, Planning feed speed in cold ring rolling, International Journal of Machine Tools and Manufacture , 47 — Huang, Ring rolling theory and technology, China machine press, Beijing, China, The finite element model of hollow shaft and shaft sleeve was established, and the equivalent stress and contact stress were computed after interference assembly. There were children who received a port.
