Molecular Dynamics Study of the Structural and Thermodynamic Properties of Si...
In this work we observed the evolution of the structural and thermodynamic properties of silica during cooling in a temperature range from 5000 to 300K by the LAMMPS computational code. The structure 𝑆𝑖𝑂2used in this work was obtained from the Materials Project database, containing 144 atoms and with mesh parameters a=b=19.607A° and c=7.496 A° and density 1.66. The results were obtained with the use of MEAM and Buckingham potentials reflecting respectively the nature of the alloy and the effect of the SiO silica charge2. However the particularity was observed for the MEAM potential presenting a point around 4376.22K, with a volume of V=2776.242A°3 , mesh parameter Lx=19.362A° and a density =1.725. For the thermodynamic properties, we showed that the enthalpy decreased with temperature; for the interval from 5000 to 3000K we observed a random distribution of the enthalpy, this distribution was more precise for temperatures between 2000 and 300K; however the specific heat presented an average trend around 6j/(K*mol).

Micro Mechanical Modeling of Fiber / Epoxy Unidirectional Laminates Using Fea
The focus of the study was to develop the micromechanical model associated with proper damage model to predict the overall mechanical behavior of fiber/matrix unidirectional laminates. The present and first investigation studies the influence of fiber-matrix interface on the behaviour of fiber reinforced composite lamina using micromechanical models. Mechanical properties E1 and E2 are determined at various volume fractions. The second investigation studies the micro-thermo elastic behaviour of the square unit cell of a hybrid fiber reinforced composite lamina. Later this model is extended to predict the coefficients of thermal expansion of graphite-boron hybrid fiber reinforced lamina for various volume fractions.In the third investigation, an analytical solution of the thermal stresses for a fiber embedded in a matrix is presented based on the idea of the finite element and under some simplifying assumptions. The analytical solution to the problem is found for the case when the length of the embedded bar (fiber) is much greater than its radius, and the Young's modulus of the matrix is much less than that of the fiber. The problem is also solved numerically by means of finite element analysis using ANSYS 10.0. Both results are compared and it is shown that both approaches coincide very close qualitatively and quantitatively although significant discrepancies may appear at specific points for specific cases. For all above three cases 3-D finite element models have been developed from the representative volume elements of the composite which are in the form of square unit cells. The finite element software ANSYS 10.0 has been successfully executed to evaluate the properties

Material engineering1 by
Materials engineering involves designing materials to have desired properties through control of their structure and processing. It encompasses metals, ceramics, polymers, composites, and advanced materials. Metals have high strength but are electrically conductive while ceramics are strong but brittle. Polymers are lightweight but poor thermal conductors. Composites combine materials for unique properties. Processing and crystal structure determine properties like hardness, conductivity and strength. Common materials include steel alloys, concrete and plastics each suited for different applications.
Semiconductor
This document discusses semiconductors, which have electrical conductivity between conductors and insulators. Semiconductors are the foundation of modern electronics and their properties rely on quantum physics. Their conductivity increases with temperature. Common semiconductor materials include silicon, germanium, and gallium compounds. Semiconductors are made useful through doping, which introduces impurities to greatly increase the number of charge carriers within the material. This allows semiconductor devices to control and shape electrical currents.

chapter -1.pdf
The document discusses conducting polymers and their fundamentals. It begins with an introduction to conducting polymers, noting they are organic polymers that conduct electricity due to their conjugated backbone structure.

The document also discusses the classification of materials by conductivity and the mechanisms of p-type and n-type doping in conducting polymers.
Damping Of Composite Material Structures with Riveted Joints
Vibration and noise reduction are crucial in maintaining high performance level and
prolonging the useful life of machinery, automobiles, aerodynamic and spacecraft structures. It is
observed that damping in materials occur due to energy release due to micro-slips along frictional
interfaces and due to varying strain regions and interaction between the metals. But it was found
that the damping effect in metals is quite small that it can be neglected. Damping in metals is due to
the micro-slips along frictional interfaces. Composites, however, have better damping properties
than structural metals and cannot be neglected. Typically, the range of composite damping begins
where the best damped metal stops.In the present work, theoretical analysis was done on various
polymer matrix composite (glass fibre polyesters) with riveted joints by varying initial conditions.
Strain energy loss was calculated to calculate the damping in composites. Using FEA model, load
variation w.r.t time was observed and the strain energy loss calculated was utilised in finding the
material damping for Carbon fibre epoxy with riveted joints. Various simulations were performed in
ANSYS and these results were utilised to calculate the loss factor, Rayleigh‘s damping constants
and logarithmic decrement.

Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
