The Staple-Shape Plate Springs Engineering Calculation Method

A New Calculation Method for Belleville Disc Springs with Contact Flats and Reduced Thickness

A new calculation method for disc springs with contact flats and reduced thickness is presented in this paper. The analysis aims at putting in evidence the contradiction in standard norms where the standard calculation method for this kind of Belleville springs is used. On the basis of this analysis it is found that standard methods do not work for reduced disc springs because they lead to dang...

The Cedell method (cerclage wire and staple) leads to less reoperations than the AO method

BACKGROUND AND PURPOSE Fractures of the lateral malleolus often require open reduction and internal fixation (ORIF). Despite uneventful fracture healing, many patients will suffer from long-term detriments after ORIF, such as local tenderness that requires hardware removal. In Sweden, there are 2 major fixation methods, either the AO method (plate and screws) or the Cedell method (cerclage wire...

MATHEMATICAL ENGINEERING TECHNICAL REPORTS Calculation of Orthant Probabilities by the Holonomic Gradient Method

We apply the holonomic gradient method (HGM) introduced by [9] to the calculation of orthant probabilities of multivariate normal distribution. The holonomic gradient method applied to orthant probabilities is found to be a variant of Plackett’s recurrence relation ([14]). However a straightforward implementation of the method yields recurrence relations more suitable for numerical computation ...

Evaluation of the profile method for calculation of evapotranspiration

Ultralight shape-recovering plate mechanical metamaterials

Unusual mechanical properties of mechanical metamaterials are determined by their carefully designed and tightly controlled geometry at the macro- or nanoscale. We introduce a class of nanoscale mechanical metamaterials created by forming continuous corrugated plates out of ultrathin films. Using a periodic three-dimensional architecture characteristic of mechanical metamaterials, we fabricate ...
