Regularization Methods Applied to Noisy Response from Beams under Static Loading
(ASCE, 2020)The estimation of flexural stiffness from static loading test data is the basis of many methods assessing the condition of structural elements. These methods are usually developed under the assumption of having sufficiently ... -
Elastoplastic Solution to Drained Expansion of a Cylindrical Cavity in Anisotropic Critical-State Soils
(ASCE, 2020)This paper presents an elastoplastic solution for drained expansion of a cylindrical cavity in anisotropic critical-state soils. The large deformation theory and the advanced anisotropic critical-state soil model S-CLAY1, ... -
Coupled Directional Dilation–Damage Approach to Model the Cyclic-Undrained Response of Soft Clay under Pure Principal Stress Axes Rotation
(ASCE, 2020)This study presents a directional constitutive model to predict the nonproportional cyclic behavior of undrained soft clay. A novel strategy consisting of a combination of directional dilation and the damage microplane ... -
Application of Time-Frequency Interpolation and Proper Orthogonal Decomposition in Nonstationary Wind-Field Simulation
(ASCE, 2020)The spectral representation method is widely used to generate nonstationary processeses. However, the operations of Cholesky decomposition in two directions and double summations are fairly time consuming. Moreover, the ... -
3D Elastoplastic Model for Fine-Grained Gassy Soil Considering the Gas-Dependent Yield Surface Shape and Stress-Dilatancy
(ASCE, 2020)Fine-grained sediments containing large discrete gas bubbles are widely distributed in the five continents throughout the world. The presence of gas bubbles could either degrade or enhance the hardening behavior and undrained ... -
Effective Anisotropic Elastic and Plastic Yield Properties of Periodic Foams Derived from Triply Periodic Schoen’s I-WP Minimal Surface
(ASCE, 2020)Recently, there has been a growing interest in studying cellular materials made of unit cells that take the topology of the mathematically known triply periodic minimal surfaces (TPMS). Architected foams based on the ... -
Microstructural Origins of Wave Modulus of Elasticity of Concrete
(ASCE, 2020)Nondestructive ultrasound-based methods have been applied to evaluate the elastic properties of concrete materials. Although the wave modulus of elasticity of concrete frequently is reported to be higher than the static ... -
A Comprehensive Study on Nonlinear Functionally Graded Piezoelectric Harvesters under Moving Loads
