Structural elements which are deformed under load occur in many fields of technology. Conventional resilient elastic deformation behavior of structural elements is a result of a force action which correlates with the direction of the force acting on the structural element. For some design requirements a shape change of the component in a direction opposite to the force action direction is desirable. <br><br> <strong>Technology</strong><br> This is a load-adaptive element comprising at least one trapezoidal, elastically movable four-bar hinge. The four-bar hinges have recesses for forming hinge points that are produced by weak points in the material and embody elastic bending hinges and slot-like recesses connected to the hinge points. Successive, mutually spaced four-bar hinges form a multi-hinge mechanism. Shape change behavior in the component is generated, which is anisotropically resilient elastic and directed counter to the action of the force. It can be used for components which are loaded on one side or on alternate sides.

Spring is here and ectotherms, or animals dependent on external sources to raise their body temperature, are becoming more active. Recent studies have shown...
Glass-fronted office buildings are some of the biggest energy consumers, and regulating their temperature is a big job. Now a façade element developed by Fraunhofer researchers and designers for glass fronts is to reduce energy consumption by harnessing solar thermal energy. A demonstrator version will be on display at Hannover Messe.
In Germany, buildings account for almost 40 percent of all energy usage. Heating, cooling and ventilating homes, offices and public spaces is expensive – and...
Outstanding chemical, thermal and tribological properties predestine silicon carbide for the production of ceramic components of high volume. A novel method now overcomes the procedural and technical limitations of conventional design methods for the production of components with large differences in wall thickness and demanding undercuts.
Extremely hard as diamond, shrinking-free manufacturing, resistance to chemicals, wear and temperatures up to 1300 °C: Silicon carbide (SiSiC) bundles all...
In an experiment at the Department of Energy's SLAC National Accelerator Laboratory, scientists precisely measured the temperature and structure of aluminum as...
The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
