Failure in plain and reinforced concrete—an analysis of crack width and crack spacing
International Journal of Solids and Structures, 1996 The proper prediction of crack widths in plain concrete and the spacing of primary cracks in reinforced concrete are the subject of this paper. Attention is focused on the influence of the crack concept. A comparison has been made between the standard crack model, the crack model with the fracture energy as a separate parameter, the rate-dependent ...

Using 3D-Printed Formwork to Enable Controlled Crack Creation in Concrete Specimens
CivilEngThe employment of automated non-destructive testing (NDT) methods for crack characterization in concrete, needs calibration and benchmarking in a controlled environment. This requires test specimen with comparable and ideally reproducible cracks. To this

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs
Advanced Engineering Materials, EarlyView.This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Crack opening stretch in a plate of finite width [PDF]
The problem of a uniaxially stressed plate of finite width containing a centrally located damage zone is considered. It is assumed that the flaw may be represented by a part-through crack perpendicular to the plate surface, the net ligaments in the plane

Shear-lag analysis of a hybrid, unidirectional composite with fiber damage [PDF]
, 1983 Development of a method of analysis capable of predicting accurately the fracture behavior of unidirectional hybrid (buffer strip) composite laminates was studied. Three particular solutions are discussed in detail: broken fibers in a unidirectional half-

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]
, 2011 Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
