In engineering, cracks are typically regarded as defects due to enormous stress amplification at tip of the crack. Conversely, scorpion ingeniously utilizes the “risky” near-tip stress field of a crack-shaped slit to accurately detect weak vibration signal without causing catastrophic crack propagation from the slit tip. The present paper focuses on the balance strategy between structural safety and sensing accuracy of slit-based mechanical sensilla. We performed a detailed structural and mechanical property study of tissue around the slit wake utilizing a complementary combination of various experimental methods. The results indicate that there is a special thin surface membrane covering the slit wake and the elastic moduli of the membrane and exoskeleton are 0.562 GPa and 5.829 GPa, respectively. In addition, the ratio of bending stiffness between exoskeleton and membrane tissue is about 8 × 104. The theoretical and simulation analysis show that the surface membrane—with appropriate elastic modulus and bending stiffness—can achieve different forms of deformation with the change of slit width for protecting the mechanosensory structure without sacrificing the sensing accuracy. This finding offers a crucial theoretical basis for the further design of bionic mechanical sensors based on the near-tip stress field of artificial cracks.

The distribution of residual stress in hot rolled large size H-beams is complex due to the uneven temperature distribution on the final rolling cross-sections. In this paper, 3D simulation analysis is conducted on the residual stress field of cooled large H-beams and the transformation of residual stress field during the flange cutting based on the calculations of thermo-mechanical coupling whole rolling process. There are tensile stress in the flange and web connection areas and compressive stress in web. During the flange cutting process, tensile stress increases suddenly when the kerf arrives at the flange and web connection area, resulting in the brittle fracture of the web. The method of controlling the residual stress of large H-beams is also simulated. Improvement in the distribution of residual stress is achieved through the forced cooling of the outside flange or reduction of the temperature differences on the final rolling cross-sections.

Simulation Results

There are different blasting stress field which around the blast hole caused by different charge when explosives exploded in the rock. Simulation analysis on borehole wall pressure and explosion stress field of rock at different charging structure was done by ANSYS/LS-DYNA. The simulation results indicate: stress of coupling charge is the maximum, water-decouple charge is the latter and air-decouple charge is the minimum; and whether air-decouple or water-decouple charge, peak stress value of model decreased along with the increasing of decouple coefficient, but the air-decouple charge show more obvious. Therefore, water-decouple blasting has good energy utilization.

Lance injected desulphurization become ineffective when injection ports become obstructed. In this work, the difference of the flow fields between single and double hole injection was investigated by numerical simulations. When one of the openings in a T-shaped injection lance is blocked, a dead zone occurs in the ladle over approximately 1/4th of the volume, and there is not an active flow field on the surface of clogging side. To decrease clogging, industrial experiments examining different diameter lances were carried out. The results showed that clogging can be reduced by increasing the injection pressure and optimizing the injection hole diameter to be approximately 10 times the particle size of desulphurizer.
