“…For sound synthesis, Ren and colleagues [2013] extracted Rayleigh damping parameters from a single audio sample. Recently, the work was extended by [Sterling and Lin 2016] to t the parameters of the Caughey damping [Caughey 1960;Caughey and O'Kelly 1965], which gives frequency-dependent damping ratios. To capture real-world deformations, Wang and her colleagues [2015] used heterogeneous corotational linear materials and optimized Rayleigh damping parameters.…”

“…However, di erent deformations typically present varying damping behaviors. A typical example are the frequency-dependent mode decay ratios observed in sound modal synthesis [Sterling and Lin 2016]. To create an animation, in artist endeavors, we typically envision desired dynamics on a few (low-frequency) primary vibrations.…”

“…Rayleigh damping is arguably the most widely used damping model in FEM simulation [Rayleigh 1896]. To improve sound simulation quality, Sterling [2016] presented a modal synthesis technique that uses generalized proportional damping (GPD) to capture frequency-dependent linear damping. However, to the best of our best knowledge, there has not been any previous work to procedurally model plant damping.…”

Botanical simulation plays an important role in many fields including visual effects, games and virtual reality. Previous plant simulation research has focused on computing physically based motion, under the assumption that the material properties are known. It is too tedious and impractical to manually set the spatially-varying material properties of complex trees. In this paper, we give a method to set the mass density, stiffness and damping properties of individual tree components (branches and leaves) using a small number of intuitive parameters. Our method is rooted in plant biomechanics literature and builds upon power laws observed in real botanical systems. We demonstrate our materials by simulating them using offline and model-reduced FEM simulators. Our parameters can be tuned directly by artists; but we also give a technique to infer the parameters from ground truth videos of real trees. Our materials produce tree animations that look much more similar to real trees than previous methods, as evidenced by our user study and experiments.

“…Through parameter adjustment, the linear structural model provides an efficient way to approximate the modal frequency and damping, and compute the structural response if the conditions are similar to experimental ones [1][2][3][4][5][6]. However, there are two major problems with this approach.…”

In factory-assembled structures, the bolted joint is the cause of local energy dissipation and flexibility, and its dynamics influences the dynamics of the whole structure. This paper puts forward a method to simulate the dynamics of bolted joint based on the thin-layer element (TLE) of nonlinear material. First, a finite-element model was built for an isolated bolted joint. Then, the tangential force-displacement curve of the bolted joint was obtained through an experiment on a universal testing machine (UTM) to reflect the features of the joint. On this basis, the response surface methodology (RSM) and the genetic algorithm (GA) were combined to identify the parameters of the material in the finite-element model. The simulated force-displacement curve agrees well with that measured through experiment. Our approach facilitates the precise prediction of the dynamics of factory-assembled structures with complex joints.
