A 70-year-old woman was admitted to our hospital with a complaint of bulging in the right lower portion of the abdomen. The bulging was in accordance with an old operative scar for appendicitis. The findings of computed tomography (CT) showed defects in the abdominal muscles and the protrusion of the intestine into the subcutaneous fat. The patient was diagnosed with incisional hernia after app...

The problem of localized bulging in inflated membrane tubes shares the same features with a variety of other localization problems such as formation of kink bands in fibre-reinforced composites and layered structures. This type of localization is known to be very sensitive to imperfections, but the precise nature of such sensitivity has not so far been quantified. In this paper, we study effect...

BACKGROUND The need for a safer lower-lid blepharoplasty procedure than the classic subciliary approach has long been recognized. In 1996, de la Plaza and de la Cruz first theorized septal suturing via a transconjunctival approach that preserves both muscle and infraorbital fat. This is the first report of a series of patients treated with this technique. The transconjunctival approach can avoi...

Inchworm based on the voltage actuation of dielectric elastomer actuators (DEAs) are amongst the simplest types of robots. We demonstrate a proof-of-concept inchworm robot that incorporates a few aligned fibers to suppress undesirable actuator bulging and more effectively convert the bending of a dielectric elastomer unimorph to forward motion. Finite element modeling confirms the role of the f...

High-pressure tube hydroforming is a promising method to deform the tubes in various shapes by bulging applying high internal pressure. However, challenges lie process itself, i.e., requires an expensive pump system and brings excessive thinning deformed part section. One option reduce required pressure solve these difficulties, other provide axial feed deformation zone thinning. due higher loa...

We proposed a local one-sided rubber bulging method of metal tubes to evaluate various strain paths at an aimed portion and measured the forming limit strains place occurrence necking under biaxial deformation. Using this method, since is used give pressure from inner side tube, no sealing mechanisms were necessary unlike during hydraulic bulging. An opening was prepared in front die locally bu...
