Typically, structures fail due to buckling if loaded by compression. However, it is important to notice that-especially in lightweight structures-there are several situations in which instabilities, such as buckling or wrinkling, can be observed under tensile loads. In the present paper, a number of problems, dealing with buckling under tensile loads, are presented. Some solutions already contained in former papers of the author are reconsidered, compared to recent results, and extended. Further new results are presented. Bifurcation buckling under tensile loading of beams, plates (with and without cut-outs), rolled metal strips, thin cell walls of metal foams, and of thin metallic films on polymer substrates is treated in this paper. It is made clear that in all cases of buckling under tensile loads eventually compressive stresses are responsible for the loss of stability. Thus, one should carefully differentiate between "buckling under tension" and "buckling under tensile loads". Nonconservative loads as well as material instabilities under tension, such as necking, are not considered in this paper.

A novel platform for in situ investigation of cells and tissues under mechanical strain

The mechanical micro-environment influences cellular responses such as migration, proliferation, differentiation, and apoptosis. Cells are subjected to mechanical stretching in vivo, e.g., epithelial cells during embryogenesis. Current methodologies do not allow high resolution in situ observation of cells and tissues under applied strain, which may reveal intracellular dynamics and the origin of cell mechanosensitivity. We have developed a novel polydimethylsiloxane (PDMS) substrate capable of applying tensile and compressive strain (up to 45%) to cells and tissues while allowing in situ observation with high resolution optics. The strain field of the substrate was characterized experimentally using digital image correlation (DIC) and the deformation was modeled with finite element method (FEM) using a Mooney-Rivlin hyperelastic constitutive relation. The substrate strain was found to be uniform for greater than 95% of the substrate area. As a demonstration of our system, we applied mechanical strain to single fibroblasts transfected with GFP-Actin and whole transgenic Drosophila embryos expressing GFP in all neurons during live imaging. We report three observations of biological responses due to applied strain: (1) dynamic rotation of intact actin stress fibers in fibroblasts; (2) lamellipodia activity and actin polymerization in fibroblasts; (3) active axonal contraction in Drosophila embryo motor neurons. Our novel platform may serve as an important tool in studying the mechanoresponse of cells and tissues including whole embryos.

“…The plates had different sizes and were numerically simulated by means the Finite Element Method (FEM). Shimizu (2007) has showed that, when a plate is perforated, compression stresses appear locally near the hole under a tensile load, and the compression stress may cause local buckling -it´s so called tension buckling of the plate. Moen and Schafer (2009) developed expressions to represent the influence of holes under the critical buckling load in bent or compressed plates.…”
