Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... Per saperne di più
Strain gauges have been extensively used for detecting strain in various applications. Double-ended tuning fork (DETF) strain gages present better performance characteristics than standard foil gauges, including higher sensitivity, smaller size and higher resolution. This study focuses ... Per saperne di più
To investigate the thermal-mechanical behavior of oceanic transform faults, we calculate 3-D steady-state incompressible mantle flow and heat transport using COMSOL Multiphysics. Our model incorporates a nonlinear viscous rheology with a visco-plastic approximation to simulate ... Per saperne di più
Finite element method (FEM)-based solutions are known to contains errors and uncertainties due to at least four mathematical (M) and four physical (P) sources, namely, (M-1) mesh density or degrees of freedom, (M-2) mesh element types, (M-3) mesh quality such as mean aspect ratio, (M-4) ...

Evaluation of J-integral in three dimensional bimodular stress field has been carried out for a cracked three point bend specimen having properties of nuclear grade graphite (2020). The additional area integral has an important role in J-integral. The stress dependent elasticity ... Per saperne di più
Cereal foods can be considered as cellular solids: texture is defined by their structure and mechanical properties [1]. Elderly people show a significant alteration of oral health [2] and salivation [3], causing difficulties to eat. Therefore, there is a need to understand chewing ... Per saperne di più
2D-modeling of arc welding in butt-joint configuration was performed in this study considering thermal-structural interactions. Thermal behavior was modeled in COMSOL Multiphysics® using the Heat Transfer Module with weld heat input as a Gaussian pulse whereas structural behavior using ... Per saperne di più
During the hydraulic fracturing process, there can be possible re-activation of closed/sealed faults and natural fractures in the formation, which may lead to changes in the boundary conditions of the reservoir. While study models of shale gas formations have utilized the concept of a ... Per saperne di più
The dumbbell geometry is an ideal shape for testing the compressive strength of advanced ceramic materials. This paper details the combined use of COMSOL Multiphysics® and LiveLink™ for MATLAB® for determining the elastic properties of dumbbell-shaped samples by measuring their acoustic ...

油藏在生产过程中，地层中的孔隙压力下降，压力降由井筒开始向外传播，从而导致地应力场的分布发生变化，后期钻新井的最优位置将因此发生改变，所以必须明确生产过程中油藏地应力场的变化规律。 不考虑储层的温度变化，所建模型只需要进行固体力学与达西渗流场的耦合。对于目前中国的油藏开发情况，地层渗透率较低，单个开发储层较薄，常采用压裂方式增产，将储层看做纵向均质的地层，因此可以使用二维模型。 建立地层为 300m×300m 的矩形区域，井筒为 0.1m 的圆形区域，二者差集为所建的模型。对整个模型区域施加固体力学场和 Darcy 渗流场。因为设置求解应力场为应力的变化量 ...
