Iosipescu Shear Test

The stress field arising in tensile loading of the Iosipescu shear test is analyzed by means of finite element method. In a parametric study on a composite laminates-adhesive joint, the tensile loading method is shown more effective in creating a pure shear stress field with negligible normal stresses in the notched area than the conventional compressive loading method, although the maximum shear stress is marginally higher for the former method than the latter.

Different geometries of shear test specimens were experimentally and numerically investigated. They are used for calibration of a virtual model, to be used for sheet metal blanking. Different specimen configurations were simulated in order to determine the strain and stress fields and the potential of producing pure shear failure. Tensile and shear tests were performed using DC01 steel material. The experimental data are used later to calibrate a material with Johnson-Cook elastic-plastic model.

Polyurethane stoppers are used to protect heavy parts from damage in case of an unpredicted impact between parts in a robot. In order to evaluate the performance of a polyurethane stopper during impact, it was necessary to model the material behavior. Thus, the compression test, the tension test, the pure shear test, the torsion vibration test were conducted, and the hyperelastic material constants and viscoelastic material constants (Prony series parameters) were determined. Finite element simulations for the tests were conducted to check whether the material model adequately represented the material behavior. In addition, a finite element simulation for an impact between a part of a robot and a stopper was conducted to evaluate the performance of a stopper.

Clearing Temperature

Liquid crystal elastomer (LCE) has been recently explored extensively to make diverse active structures and devices. Depending on synthetic process, LCE can be made either polydomain or monodomain when ambient temperature is below isotropic clearing temperature. In the applications, LCE may be subjected to large mechanical stretch or force and break apart. The capability of predicting the rupture of LCE under different loading conditions is crucial for the applications. However, according to our knowledge, there is no report on fracture energy measurement of LCE. In this paper, we measured fracture energy of both monodomain and polydomain LCEs using pure shear test. We found that polydomain LCE has significantly higher fracture energy than monodomain one. We suggest that the increase of fracture energy in polydomain LCE is attributed to stretch-induced polydomain-to-monodomain transition near the crack tip of the material.

Near Future

The reinforcement of concrete structures with laminates of carbon fibers CFRP (Carbon Fiber Reinforced Polymer) began in the 1970’s but laminates were not used extensively until the 1990’s.Nowadays it is one of the most promising technologies due to the good mechanical characteristics of the laminates and their easy manipulation. In the near future, laminates will play a fundamental role in the rehabilitation projects of buildings. Laminates bond to the concrete by means of resins of epoxy type. The capability of the reinforcement depends directly on the proper behavior of the interface laminate-concrete. The laminate helps to bear loads while the concrete is able to transfer stresses to the laminate. The safety factor of the reinforcement can be guaranteed if we can predict the behavior at the interface between both materials. In this work a test of pure shear has been developed to better understand the behavior at the interface between the laminate and the concrete.
