“…The studies of multifield coupling phenomena (MCP) are important for functional and structural materials because they are often operated under several external stimuli simultaneously in real applications. In the area of multifield coupling, a group of researchers have dedicated to the computational and modeling works in order to explain the fundamental coupling mechanisms, and the other stream of research has been focused on the experimental studies of MCP from macroscale to nanoscale . MCP can be found in many different applications.…”

The characterization of the local multifield coupling phenomenon (MCP) in various functional/structural materials by using scanning probe microscopy (SPM)-based techniques is comprehensively reviewed. Understanding MCP has great scientific and engineering significance in materials science and engineering, as in many practical applications, materials and devices are operated under a combination of multiple physical fields, such as electric, magnetic, optical, chemical and force fields, and working environments, such as different atmospheres, large temperature fluctuations, humidity, or acidic space. The materials' responses to the synergetic effects of the multifield (physical and environmental) determine the functionalities, performance, lifetime of the materials, and even the devices' manufacturing. SPM techniques are effective and powerful tools to characterize the local effects of MCP. Here, an introduction of the local MCP, the descriptions of several important SPM techniques, especially the electrical, mechanical, chemical, and optical related techniques, and the applications of SPM techniques to investigate the local phenomena and mechanisms in oxide materials, energy materials, biomaterials, and supramolecular materials are covered. Finally, an outlook of the MCP and SPM techniques in materials research is discussed.Multifield Coupling temperature, moisture, and atmosphere.

“…Hamel's study [98] tackled this framework solely utilizing ABAQUS through the development of a user subroutine, referred to as the user element (UEL). Within this approach, the weak forms of the radiative transfer equation and the balance of linear momentum were discretized and approximated using linear two-and three-dimensional isoparametric elements.…”

The photomechanical effect, which is characterized by light-induced mechanical deformation in materials, has gained significant attention for its potential applications across various domains. Photomechanical modeling, which involves the integration of photochemistry and mechanical behavior in photoactive materials, has emerged as a crucial tool for understanding and optimizing their functionality. In this review article, we present a comprehensive overview of recent developments in mechanical modeling and numerical simulations, with a specific focus on finite element simulations applied to organic photoactuators. Through a systematic literature search encompassing publications since the discovery of the photomechanical effect, we examined the progress made in modeling the photomechanical behavior of diverse organic photoactuators, including polymer-based, liquid-crystal elastomer (LCE), and composite photoactuators. The integration of light and mechanical constitutive models has enabled significant advancements in accurately representing the photomechanical responses of these materials. The key findings of this review encompass the methods and approaches employed for simulating light-induced deformation, factors influencing the photomechanical response, and current limitations and challenges in the field. In conclusion, the development of novel organic photoactuators necessitates the establishment of more generalized photomechanical couplings to optimize their design, enhance the light-induced response, and facilitate cost-effective commercialization. This review article aims to serve as an invaluable resource for researchers interested in this field, stimulating further investigations into the potential applications of organic photoactuators.

Shape memory polymers are a class of smart materials, which are capable of fixing their deformed shapes, and can return to their original shape in reaction to external stimulus such as heat. Also due to their exceptional properties, they are mostly used in four-dimensional printing applications. To model and investigate thermomechanical response of shape memory polymers mathematically, several constitutive equations have been developed over the past two decades. The purpose of this research is to provide an up-to-date review on structures, classifications, applications of shape memory polymers, and constitutive equations of thermally responsive shape memory polymers and their composites. First, a comprehensive review on the properties, structure, and classifications of shape memory polymers is conducted. Then, the proposed models in the literature are presented and discussed, which, particularly, are focused on the phase transition and thermo-viscoelastic approaches for conventional, two-way as well as multi-shape memory polymers. Then, a statistical analysis on constitutive relations of thermally activated shape memory polymers is carried out. Finally, we present a summary and give some concluding remarks, which could be helpful in selection of a suitable shape memory polymer constitutive model under a typical application.
