Research ArticleOpen accessPhrase in the titleAnalysis of Elastic-Plastic Contact Performance of Rigid Sphere Against a Deformable Flat-Effect of Strain HardnessV.C. Sathish Gandhi, S. Ramesh, R. KumaravelanProblem statement: The present study considers an elastic-plastic contact analysis of a rigid sphere with a deformable flat (Rigid Sphere-model) using finite element analysis. The effect of tangent modulus on the contact behavior of a no adhesive frictionless elastic-plastic contact was analyzed using commercial finite element software ANSYS. Approach: Different materials, in terms of the ratio of Young's modulus to … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 8,218 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnisotropy Influence of Cubic Solid on Dynamic Hertzian Contact Stiffness for a Vibrating Rigid IndenterJiayong TianProblem statement: Resonance-type microscopies have been widely used to evaluate the nanoscaled or microscaled surface elastic properties of materials by the resonance-frequency shifts of an oscillator, which contacts the surface of materials by a spherical tip. Approach: The tip-specimen contact is modeled to be a spring support, whose stiffness is given by the traditional Hertzian contact theory. However, because of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,711 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDirect Geometry and Cinematic to the MP-3R SystemsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Mechatronic robotic systems are today widely used worldwide to ease human work, but especially where work is dangerous, in toxic, radioactive, chemical, explosive atmospheres, without air such as underwater or in the cosmos, or in places hard to reach the man. Robots can take the tedious repetitive work under any circumstances and they can perform a difficult operation for a … …Journal of Mechatronics and Robotics, Vol. 1, Issue 1 · 23 Nov 2017 · 7,511 accessesView PDF Cite
