1. Dynamic crack propagation of granite subjected to biaxial confining pressure and blast loading
Abstract To great understanding the dynamic crack propagation of rock under in-situ stress and blasting, the static-dynamic loading experimental platform was built. With different confining pressure (0MPa, 2MPa, 4MPa, 6MPa, 8MPa) and different ratios (K) of horizontal-to-vertical pressure (0, 0.25, 0.5, 0.75, 1), nine texts have been carried out in quadrate

2. Laboratory study of dynamic mechanical characteristic of granite subjected to confining pressure and cyclic blast loading
Abstract To investigate the deformation characteristic of deep rock under cyclic blasting, the static-dynamic loading experimental equipment was set up. The dynamic strain gauges and high-speed (HS) camera were adopted to obtain strain field and the crack propagation of rock under confining pressure of 0 MPa, 5 MPa and 10 MPa. Under the one-time loading fro

3. Study on Meshfree Hermite Radial Point Interpolation Method for Flexural Wave Propagation Modeling and Damage Quantification
Abstract This paper investigates the numerical modeling of the flexural wave propagation in Euler-Bernoulli beams using the Hermite-type radial point interpolation method (HRPIM) under the damage quantification approach. HRPIM employs radial basis functions (RBFs) and their derivatives for shape function construction as a meshfree technique. The performance

4. Three dimensional Free Vibration and Transient Analysis of Two Directional Functionally Graded Thick Cylindrical Panels Under Impact Loading
AbstractIn this paper three dimensional free vibration and transient response of a cylindrical panel made of two directional functionally graded materials (2D-FGMs) based on three dimensional equations of elasticity and subjected to internal impact loading is considered. Material properties vary through both radial and axial directions continuously. The 3D g

5. Variations in ultrasonic wave velocity with moisture content / Velocidade de propagação de ondas de ultra-som na madeira para diferentes condições de umidade
A madeira, sendo um material higroscópico, tem suas propriedades mecânicas e elásticas afetadas por condições ambientais. Sendo assim, a relação de dependência de propriedades da madeira com a variação do teor de umidade tem merecido, há muito tempo, a atenção de pesquisadores de todo o mundo. Um dos grandes avanços obtidos nos últimos anos na

6. Direct evidence for local oscillatory current sources and intracortical phase gradients in turtle visual cortex
Visual stimuli induce oscillations in the membrane potential of neurons in cortices of several species. In turtle, these oscillations take the form of linear and circular traveling waves. Such waves may be a consequence of a pacemaker that emits periodic pulses of excitation that propagate across a network of excitable neuronal tissue or may result from cont
