TL;DR: In this paper, a novel sealing device that has a minimal effect on the mechanical behavior of concrete specimens is proposed, which connects one side of silicon plates to a specimen using two specially designed clamps, instead of adhesive and screws the other side of the plates together to a steel plate.

TL;DR: In this paper, an extended finite element method (XFEM) was used to extract the dynamic stress intensity factor (DSIF) for structures containing multiple discontinuities (cracks, voids and inclusions).

TL;DR: In this article, a long-term field measurement was carried out during excavating and backfilling construction of an anchored sheet pile wall structure, and the results indicated that the lateral earth pressure from the soil drove the deformation of the anchored sheet piles and that the soil movement acted as a “damper” to slow down deformation processes by resisting the tubular pile in the soil-structure interaction system.

TL;DR: In this paper, a vibration damper for a photonic crystal with an adjustable cell property period array is proposed, where the influence of a photonics crystal weak joint interface (or interface layer) on a band gap is considered, the controllability of physical and mechanics parameters under magnetorheological elastomers field conditions is utilized, and an appropriate mechanism is built, and a controllable cell material physical property and interface layer geometrical parameters are obtained, so that the random vibration control photonic crystals variable band gap range suitable for multiple working condition control structure system

TL;DR: The inhomogeneity of materials and the inertial effect were considered as the main factors in the strength enhancement of concrete together with a proposed dynamic model and the initial elastic modulus and tensile strength of concrete showed obvious rate sensitivity.
