A Frequency-Domain Method for Determining Joint Stiffness in a Rock Mass Using Stress Wave Response

Abstract Accurate determination of joint stiffness is crucial for evaluating the deformation and stability of rock mass in geotechnical engineering. This study proposes a novel method for determining joint stiffness by analyzing the frequency characteristics of the stress wave. P...

Numerical modeling for generating ultrahigh porosity aluminum foam through independent control of pore size and cell wall thickness

This paper proposed a numerical modeling method for generating ultrahigh porosity aluminum foam through independent control of pore size and cell wall thickness. The proposed method introduced two independently adjustable parameters (point spacing and scaling distance) to control...
