چکیده
The article addresses the mathematical modeling of folding a thin elastic sheet along prescribed curved arc. A rigorous model reduction from general hyperelastic material description is carried out under appropriate scaling conditions on energy and geometric properties arc in dependence small thickness. resulting two-dimensional piecewise nonlinear Kirchhoff plate bending with continuity condition at discontinuous Galerkin method an iterative scheme are devised for accurate numerical approximation large deformations.

Tetracycline (TC) is a broad spectrum of antibiotic which is used to cure infectious diseases and cancer. It can cause harmful side effects due to its high absorption in all organs. On the other hand graphene is appropriate to carry drug and release it to special target, organ or cell. It may decrease the side effects of the drug dramatically by using low dosage of medicine. Graphene oxide (GO)...
متن کاملSingular thin viscous sheet.
The evolution of a thin viscous layer is usually smooth. Here we conduct an experiment where the layer adopts a singular shape. Using the analogy between the flow of a viscous liquid and the deformation of an elastic solid, the theoretical analysis predicts a conical shape for the sheet and is in quantitative agreement with the experiment.
متن کاملCrumpling a thin sheet.
Crumpled sheets have a surprisingly large resistance to further compression. We have studied the crumpling of thin sheets of Mylar under different loading conditions. When placed under a fixed compressive force, the size of a crumpled material decreases logarithmically in time for periods up to three weeks. We also find hysteretic behavior when measuring the compression as a function of applied...
متن کاملExperimental Study of Sable Crack Growth in Thin Aluminium Sheet
Recent failure information from research teams in NASA Langley and others has shown that CTOA based fracture models calibrated on large C(T) and M(T) specimens can be transferred successfully to cracked aircraft fuselage structures for the assessment of their residual strength. A major difficulty that could limit the more extensive use of this failure parameter is its experimental measurement e...
