“…There are many ways of characterizing viscoelasticity, [47][48][49] but one relatively simple approach is to measure stress relaxation. In this form of testing, a high tensile strain is rapidly applied to a test specimen and held constant for a period of time, during which stress is measured.…”

This work presents a comprehensive open-source simulation and design tool for Soft pneumatic actuators (SPAs) using finite element method, compatible and extensible to a diverse range of soft materials and design parameters. Thorough characterization of the hyperelastic and viscoelastic behavior is illustrated using a sample soft material (Ecoflex 00_30), and an appropriate material constitutive law. SPA performance (displacement and blocked-force) are simulated for two types of SPA and validated with experimental testing. Real-world case studies are presented in which SPA designs are iteratively optimized through simulation to meet specified performance criteria and geometric constraints.

“…Indeed, mechanical properties of polymers may dramatically depend on the specific synthetic procedure and the aging of the material. Also, viscoelastic response is frequency dependent and thus a certain discrepancy may result from the different frequency ranges of CR-AFM and DMA [6,46]. Finally, CR-AFM and DMA generally probe different volumes of sample under the surface.…”

“…DMA can be performed at variable temperature, e.g., the so-called dynamic mechanical thermal analysis (DMTA), allowing for instance the identification of glass transition and other thermal transitions in polymeric materials [5]. Also, based on atomic force microscopy (AFM), counterparts of DMA have been developed which enable the characterization of viscoelastic materials at sub-micrometer and nanometer scale [6]. Due to its high spatial resolution, nanometer dimensions of the probed volume of materials, and nondestructive nature of measurements, AFM is currently a broadly used tool for the mechanical investigation of polymers community.…”

Abstract. Characterization of mechanical properties at the nanometer scale at variable temperature is one of the main challenges in the development of polymer-based nanocomposites for application in high temperature environments. Contact resonance atomic force microscopy (CR-AFM) is a powerful technique to characterize viscoelastic properties of materials at the nanoscale. In this work, we demonstrate the capability of CR-AFM of characterizing viscoelastic properties (i.e., storage and loss moduli, as well as loss tangent) of polymer-based nanocomposites at variable temperature. CR-AFM is first illustrated on two polymeric reference samples, i.e., low-density polyethylene (LDPE) and polycarbonate (PC). Then, temperature-dependent viscoelastic properties (in terms of loss tangent) of a nanocomposite sample constituted by a epoxy resin reinforced with single-wall carbon nanotubes (SWCNTs) are investigated.

“…AFAM has been recently extended to the study of such materials by developing suitable models for the analysis of experimental resonance curves to extract storage and loss moduli [103,104]. The capability of SMM of allowing the evaluation of E and E of polymeric samples has been recently demonstrated by comparison with standard DMA measurements [53,105]. Finally, the quantitative measurement of contact stiffness, quality factor, and damping and their dependence on the applied load enable the investigation of friction [106,107].…”

In this chapter, which serves as an introduction to the entire book, an overview is given of techniques resulting from the synergy between ultrasonic methods and scanning probe microscopy (SPM). Although other acoustic SPMs have been developed, those reviewed in this book are either the earliest proposed techniques, which are most widespread, extensively used, and continuously improved, or have been recently developed, but have been proved to be extremely promising. The techniques are briefly introduced, emphasizing what they have in common, their differences, their capabilities, and limitations.
