A novel frequency domain assurance criterion, called hereby Spectral Assurance Criterion (SAC), is proposed for frequency response analysis of cracked piezoelectric beam under moving load. First, a model of cracked beam bonded with a piezoelectric layer under moving harmonic load is conducted based on the double beam conception and then, analytical expressions of midspan beam deflection (mechanical response) and output charge produced in the piezoelectric layer (electric response) has been established in the frequency domain.

This paper presents a theoretical study that describes the fiber bridging mechanism under tensile stress using a closed-form analytical function. This proposed analytical model allows estimating the stress at a crack opening where the fiber orientation is represented by a Gaussian-like periodic distribution function.

The mode I and mode II fracture behavior of a single-layer graphene sheet (SLGS) containing a center crack was characterized with the results of an finite element method (FEM) and an analytical model. Finite element method based micromechanical analysis is used to understand the fracture behavior of functionally SLGS.

Tensile properties of strain-hardening fiber-reinforced concrete are the key engineering parameters in determining bending resistance of the material. In this paper, an analytical model to predict tensile properties of ultra-high-performance fiber-reinforced concrete, a type of strain-hardening fiber-reinforced concretes, was performed based on single fiber pullout test.

This paper presents the experimental characterization and analytical modeling for fire performance of carbon TRC under the thermomechanical regime at constant tensile force. The carbon TRC is manufactured from the cementitious matrix with good thermal properties (refractory matrix) and the reinforcement of carbon textiles.
