Google Maps/Earth Computer Graphics Algorithms for Model Reduction in Mechanics of Materials

Submitted by karelmatous on

We present an innovative image-based modeling technique, based on Google Earth like algorithms, to effectively resolve intricate material morphology and address the computational complexity associated with heterogeneous materials. This sharp volumetric billboard algorithm stems from a volumetric billboard method, a multi-resolution modeling strategy in computer graphics. In this work, we enhance volumetric billboards through a sharpening filter to reconstruct the statistical information of heterogeneous systems.

Arc Length Continuation method fails at low arc length values.

Submitted by maharshi.kintada on

I have implemented a Arc length continuation method for material non-linearity. The program quits with low arc length values while it progresses well for high arc length values. I am attaching a png image for your understating  about the nature of the force deformation curve. Can you please clarify me about the problem and provide me any suggestions on it.

Thanks in advance.

Cyclic response of friction damped mechanical systems - PhD thesis - part II

Submitted by Antonio Papangelo on

This is the "part II" of my PhD thesis.

It addresses the problem of finding the dynamic cyclic response of mechanical systems experiencing dry friction with a particular focus on the influence of varying normal and tangential loads. I first start from a single degree of freedom model and gradually increase the complexity of the system. In the last chapter I address a system with 12 degrees of freedom which shows localized vibration states, that are very similar to solutions known in other physics fields like optics and fluid dynamics. 

Stick-Slip transition in dry friction - PhD thesis -part I

Submitted by Antonio Papangelo on

This is the "part I" of my PhD thesis.

It addresses the problem of the stick-slip transition at an interface experiencing dry friction taking inspiration from the experiments led by Prof. Fineberg, where for the first time, an high speed camera has been used to visualize how the contact interface evolves when stick-slip transition occurs.
