“…An MTS model 42 table-top microtensile testing system with 50N (sensitivity: 0.01N) and 2KN (sensitivity: 0.5N) load cells was used to conduct the quasistatic tensile tests for simply supported rectangular thin films. 1,14,15 A high-speed camera (Basler piA640-210gm) with 100 photos/second (max. 210 photos/second at resolution ratio 640 × 480 dpi) was adopted to monitor the whole process of wrinkling from nonlinearly elastic, plastic behavior to final failure.…”

“…Pre-wrinkled conductive films have been used in micro-scaled modern technology in large-area electronics, capacitors, and polymer actuators, 7,8 and in medical surgery involved in treating wrinkling skin cases. 9 In addition to skin aging and wound healing, thin film wrinkling can be found in other fields such as semiconductor technology, 10 sandwich structure failure as face wrinkling, 11 stretchable connectors, 12 topographic matrices for cell alignment in bioengineering, metrology of material properties, 13,14 stretched thin sheets, [15][16][17][18][19] sheet metal forming and patterning, and topographical surface structuring. [20][21][22][23] From the numerous literature survey some related references are illustrated for example.…”

The stretch-induced wrinkling of thin films is solved through the modified von Kármán large deflection equations by first selecting the suitable deformation expressions that satisfy boundary conditions. Then, adopting the principle of minimum potential energy we obtain the deformations of simply supported rectangular thin films. The obtained significant deflections are nonlinearly elastic and of the lowest order of infinite solutions. The parameters of aspect ratio, the thickness and material of thin films are studied analytically and numerically. The highlighted results of wrinkle amplitude and load are in good agreement with experiments. The methodology also indicates the limit load impending plasticity and predicts the applied load precisely for each wrinkle. Further, it can be extended to the variety of multifunctional orthotropic and multi-layered thin films.

“…The other one is the experiment method based on the non-contact measurement technique. At present, the wrinkling experimental measurement is mainly to gain the wrinkling configuration, such as laser scanning method [5], fringe projection method [6], photogrammetry method [7][8][9]. However, these methods can not acquire the strain state for large high precision membrane structures.…”

Prediction of wrinkling characteristics is strongly correlated with the strain perpendicular to wrinkling direction. In this paper, the strain field of wrinkled membrane is tested by VIC-3D system based on the digital image correlation technique. Experimental results are validated by the tension wrinkling simulation. The experimental strain perpendicular to wrinkling direction is analyzed in depth. The wrinkling strain of a square wrinkled membrane under corner tension is extracted from experimental strain perpendicular to wrinkling direction. A quantitative characterization format of the experimental wrinkling strain is proposed. A modified prediction method of wrinkling amplitude is presented based on the experimental wrinkling strain. The results show that the precision of modified prediction model has improved 13.2% compared with the classical prediction model. The results reveal that the modified model can give an accurate prediction of the wrinkling amplitude.

“…After being wrinkled, a membrane almost loses the (in-plane) stiffness and stress (which is negative with a very small magnitude) in the direction perpendicular to wrinkles and undergoes a great change in its configuration and stress state. As it obtains the resistance to out-of-plane deformation mainly from tensile stress, wrinkling deformation can reduce the out-of-plane stiffness and play an important role in its dynamic behavior (Li et al , 2012).…”

Purpose This paper aims to numerically study the effects of boundary conditions, pre-stress, material constants and thickness on the dynamic performance of a wrinkled thin membrane. Design/methodology/approach Based on the stability theory of plates and shells, the dynamic equations of a wrinkled thin membrane were developed, and they were solved with the Lanczos method Findings The effects of wrinkle-influencing factors on the dynamic performance of a wrinkled membrane are determined by the wrinkling stage. The effects are prominent when wrinkling deformation is evolving, but they are very small and can hardly be observed when wrinkling deformation is stable. Mode shapes of a wrinkled membrane are sensitive to boundary conditions, pre-stress and Poisson’s ratio, but its natural frequencies are sensitive to all these five factors. Practical implications The research work in this paper is expected to help understand the dynamic behavior of a wrinkled membrane and present access to ensuring its dynamic stability by controlling the wrinkle-influencing factors. Originality/value Very few documents investigated the dynamic properties of wrinkled membranes. No attention has yet been paid by the present literature to the global dynamic performance of a wrinkled membrane under the influences of the factors that play a pivotal role in the wrinkling deformation. In view of this, this paper numerically studied the global modes and corresponding frequencies of a wrinkled membrane and their variation with the wrinkle-influencing factors. The results indicate that the global dynamic properties of a wrinkled membrane are sensitive to these factors at the stage of wrinkling evolution.
