A prosthetic foot is a key element of a prosthetic leg, literally forming the basis for a stable and efficient amputee gait. We determined the roll-over characteristics of a broad range of prosthetic feet and examined the effect of a variety of shoes on these characteristics. The body weight of a person acting on a prosthetic foot during roll-over was emulated by means of an inverted pendulum-l...

Roll-to-roll large-format coating and UV embossing processes aim to revolutionise the manufacturing of functional films, with the ability to process a largearea at one time, resulting in high throughput and cost reduction. In this article, we present the experimental results obtained during the process development for roll-toroll large-format coating and UV embossing. We have investigated key a...

The peak strain (PS) of sheet metal highly affects the process design and quality roll formed product. Different from traditional forming technology (RFT) that all cross section contours product are rolled simultaneously, a symmetric RFT is developed with respect to corrugated channels avoid defects like tearing, twist, redundant deformations. behaviors their strains subsequently simulated fini...

the effect of pre-existing nano sized precipitates on the mechanisms and rate of grain refinement has been investigated during the severe plastic deformation. a binary al–0.2sc alloy, containing coherent al3sc particles, of 3.62 nm in diameter has been deformed by accumulative roll bonding up to 10 cycles. the resulting deformed structures were quantitatively analyzed using electron backscatter...
