in the present study, the microstructural changes of a nickel based superalloy nimonic80a during a non-isothermal deformation were studied. therefore, microstructure evolutionduring hot side pressing test was predicted with combined methods of finite element analysis andprocessing map of the material. the predicted results were validated through experimentalmicrostructural studies. the results ...

This paper presents a prototype system for automated generation of deformed maps, based on a psychological model in the field of cognitive map. The system consists of two parts; map deformation and map database management. The map deformation part has two functions; road deformation and landmark relocation. In the road deformation process, each road segment is transformed in parallel and iterat...

Methods: Suppose Ø:S1->S2 is a map from the surface S1 to the surface S2, we define the derivative map of Ø is the linear map between the tangent spaces, dØ:TM(p)->TM(Ø(p)), induced by the map. Let J be the derivative map and define the deformation tensor as S=(JTJ)1/2. Instead of analyzing shape change based on the eigenvalues of the deformation tensor, we consider a new family of metrics, the...

A recent result of J. Damon’s [4] relates the Ae-versal unfoldings of a map-germ f with the KD(G)-versal unfoldings of an associated map germ which induces f from a stable map G. We extend this result to the case where the source is a complete intersection with an isolated singularity. In a similar vein, we also relate the bifurcation theoretic versal deformation of a bifurcation problem (map-g...

Existing map deformation techniques are mainly based on uniform grids and can be insufficient for real-time demands. For higher flexibility of allocating resolutions, we propose to use a content-aware non-uniform grid. Our contentaware non-uniform grid leads to adaptive resolutions on the map deformation. This adaptive approach results in both higher road deformability and performance. We imple...

The hot deformation behavior of a typical martensitic stainless steel containing 2.1% Ni was investigated by means of the compression test in the strain rate range of 0.001-1 s-1 and temperature range of 950-1150 °C. The flow behavior of the steel was evaluated using the flow stress curves and flow softening map and by microstructural investigation. Taking into account of the strain effect on t...
