A unified experimental-computational study on ductile fracture initiation and propagation during small punch testing is presented. Tests are carried out at room temperature with unnotched disks of different thicknesses where large-scale yielding prevails. In thinner specimens, the fracture occurs with severe necking under membrane tension, whereas for thicker ones a through thickness shearing m...

Introduction The main function of acrylic bone cement is to transfer loads from the prosthesis to the cancellous bone or increase the load carrying capacity of the surgical prosthesis. If the imposed stresses are greater than the load carrying capability, then cement fracture may occur resulting in failure of the joint replacement. The fracture of the cement mantle and subsequent premature loos...

USE OF MAUERMAYER STONE PUNCH TO TREAT POSTERIOR URETHRAL DIVERTICULA CALCULUS IN A PATIENT WITH MULTIPLE CONGENITAL ANOMALIES OF URINARY TRACT

This project is aimed to study and manufacture a novel autochecking and punch system of FPC, which is based on computer vision, image processing and automatic control technique. The system realizes the auto-punching process by a serial of workflow, including catching material, taking photos, punching, dropping material and home moving. Coordinate calibration is the core of automatic punch syste...

relatively unchanged over the last 10 years. Exophytic lesions are typically shaven, while deeper processes are sampled with a punch biopsy. However, we have found that these two techniques are often impractical and cumbersome in their application to some cutaneous morphologies.We introduce a technique which employs a punch biopsy-pen to perform a shave or “scoop” excision. This method is ideal...

Using Punch and Judy as a story domain, we describe an interactive puppet show, where the flow and content of the story can be influenced by the actions of the audience. As the puppet show is acted out, the audience reacts to events by cheering or booing the characters. This changes the emotional state of each agent, potentially causing them to change their actions, altering the course of the n...

This paper investigates the punch-through phenomenon in SiC Schottky Barrier Diodes (SBD) from capacitance–voltage (C–V) characteristics at high reverse bias voltage. High voltage bias application has not been possible by conventional measurement instrumentation. The authors, therefore, develop C–V characteristics measurement instrumentation which enables the application of high dc bias voltage...
