Functional limitations and pain are end results of scaphoid nonunion with progressive carpal collapse and radiocarpal arthritis. The aim of this study was to assess the functional outcome of four-corner arthrodesis with scaphoidectomy for the treatment of grade IV scaphoid nonunion with Scaphoid Nonunion Advanced Collapse (SNAC) stages II and III. Ten patients with symptomatic grade IV non unio...

Die corner filling is very important in tube hydroforming process. Definition of the internal pressure path is a key factor in improving the corner filling.  However, the factors that cause improvement of corner filling are still unclear. In this paper, effect of bilinear pressure path on corner filling in hydroforming of tube in box-shape die is studied using both finite element simulation and...

The study is devoted to the creation of a dataset protein structural motifs 3β-corner type. relevance and importance creating 3β-corners determined by fact that this structure can be an embryo or ready-made block in process folding, also act as independent object research field biology. contains 3β-corner-like structures are geometrically similar 3β-corners. consists 45,896 structures. For each...

A new experimental technique is proposed to measure the pressure gradient in corner laminates with aim of guiding manufacturing practices that can produce composites desired thickness. mapping sensor was placed between a metal mould tool and silicone sheet acts as an idealised composite part. The compaction loss internal corners rise external reported for first time, covering part thickness rad...

This paper reports an experimental and numerical study of the cross-sectional behaviour cold-formed high-strength steel (HSS) square rectangular hollow section (SHS RHS) members. Six stub column tests, six 3-point three 4-point bending tests have been carried out, followed by development accurate finite element (FE) models a parametric study. Based on test FE results, design rules for slender c...

Significant stress concentrations in welded structures typically arise at crack like defects and at weld toes. The geometry of the weld toe is therefore one of the primary geometrical features that control the fatigue life of welded components. This work is focused on evaluating three non-destructive methods to measure the weld toe radius: Weld Impression Analysis (WIA), Laser Scanning Profilin...
