WebSpleen stiffness: a predictive factor of dismal prognosis in liver cirrhosis. Dimitrios S. Karagiannakis 1 and Katerina Stefanaki 2 ... Among them, liver stiffness measurement (LSM) has been widely used, as it has been shown to correlate well with HVPG, though this relationship seems to weaken in values of HVPG higher than 12 mmHg, ... Web12 de set. de 2009 · I am simulating the impact of a 6mm - diameter steel solid ball with a rigid falt surface using Ansys-Lsdyna. the speed of the ball at the impact moment is low (from 1 to 10 m/s). specificly, i am intersted in the period between just touching and just leaving the ground for the first impact. Permalink John E. Dolbow on Mon, 2009-09-14 … WebBased on Eq. ~4!, the contact stiffness for smooth solids can readily be calculated and typical values for metallic surfaces are of the order of 10 GN/m, which are unrealistically high. As de-scribed in the next section, the presence of surface roughness decreases the values of the contact stiffness by several orders of magnitude. 2.2.2 Rough ... grafis background
