1. Shape Memory Alloys

Shape memory alloys (SMAs) are a type of smart material that can recover its original shape when subjected to certain stimuli, such as temperature or stress variations. Atila Fem Software enables engineers and researchers to accurately model and simulate the behavior of SMAs under different conditions.

By using Atila Fem Software, researchers can understand the thermomechanical response of shape memory alloys, predict their shape recovery capabilities, and design efficient devices utilizing this phenomenon. This software allows for in-depth analysis and optimization of SMA-based actuators, sensors, and medical implants.

2. Piezoelectric Materials

Piezoelectric materials are another class of smart materials that generate an electric charge when subjected to mechanical stress. These materials have applications in sensors, actuators, and energy-harvesting devices. The Atila Fem Software enables detailed modeling and simulation of the coupled electromechanical behavior of piezoelectric materials.

Researchers can use Atila Fem Software to optimize the design and performance of piezoelectric devices by studying their response under different load conditions. This software provides insights into the interplay between mechanical deformation, electric fields, and charge distribution, facilitating the development of more efficient and reliable piezoelectric devices.

3. Electroactive Polymers

Electroactive polymers (EAPs) are a class of smart materials that exhibit significant changes in shape or size in response to an electric field. These materials have a wide range of applications, including artificial muscles, soft robotics, and haptic devices. Atila Fem Software aids in understanding the intricate behavior of electroactive polymers.

With Atila Fem Software, researchers can simulate the electrical, mechanical, and electromechanical behavior of EAPs. This software helps in optimizing the performance of EAP-based devices by analyzing factors such as the applied electric field, material properties, and geometric configurations. It also aids in the design of complex structures, allowing for better utilization of electroactive polymers.

4. Magnetorheological Fluids

Magnetorheological fluids (MRFs) are smart materials that change their rheological properties, such as viscosity, in the presence of a magnetic field. These materials have applications in dampers, brakes, and adaptive structures. Atila Fem Software facilitates the modeling and analysis of magnetorheological fluid behavior.

Atila Fem Software allows researchers to simulate the response of MRFs under different magnetic field strengths, shear rates, and geometries. This software helps in optimizing the performance of MRF-based devices by predicting their controllable damping capabilities and analyzing the influence of various parameters. It aids in the development of efficient and highly responsive magnetorheological systems.

Smart materials offer immense potential in various industries, but their complex behavior often requires advanced simulation tools. Atila Fem Software provides engineers and researchers with the necessary capabilities to model, simulate, and optimize smart materials' performance in different applications. Whether it's shape memory alloys, piezoelectric materials, electroactive polymers, or magnetorheological fluids, Atila Fem Software proves to be a valuable tool for understanding and harnessing the potential of smart materials.

Phononic crystals (PCs) are usually defined as artificial materials made of periodic arrangement of scatterers embedded in a matrix. The band structure of PCs may present under certain conditions absolute band gaps: they display frequency ranges in which waves cannot propagate. This fact is analogous to photonic band gaps for electromagnetic waves. Therefore, such systems can be applied as noise and vibration isolation, acoustic wave guiding, acoustic filters, etc. Moreover, band structures of PCs may exhibit dispersion curves with a negative slope, inducing negative refraction phenomenon. In this chapter, the general formalism is first presented. It is applied in the second part to a phononic crystal inducing filtering application and in the last section, negative refraction of elastic waves is presented for focusing application.
