Generalizing continuous flexible Kokotsakis belts of the isogonal type
Georg Nawratil
Kokotsakis studied the following problem in 1932: Given is a rigid closed polygonal line (planar or non-planar), which is surrounded by a polyhedral strip, where at each polygon ve…
Snappability and singularity-distance of pin-jointed body-bar frameworks
Georg Nawratil
It is well-known that there exist rigid frameworks whose physical models can snap between different realizations due to non-destructive elastic deformations of material. We present…
On homotopy continuation based singularity distance computations for 3-RPR manipulators
Aditya Kapilavai, Georg Nawratil
It is known that parallel manipulators suffer from singular configurations. Evaluating the distance between a given configuration to the closest singular one is of interest for ind…
On the snappability and singularity-distance of frameworks with bars and triangular plates
Georg Nawratil
In a recent article the author presented a method to measure the snapping capability -- shortly called snappability -- of bar-joint frameworks based on the total elastic strain ene…
Evaluating the snappability of bar-joint frameworks
Georg Nawratil
It is well-known that there exist bar-joint frameworks (without continuous flexions) whose physical models can snap between different realizations due to non-destructive elastic de…
Variational Path Optimization of Linear Pentapods with a Simple Singularity Variety
Arvin Rasoulzadeh, Georg Nawratil
The class of linear pentapods with a simple singularity variety is obtained by imposing architectural restrictions on the design in such a way that the manipulators singularity var…
