A highly sensitive and selective liquid chromatography–atmospheric pressure chemical ionization tandem mass spectrometry assay was developed and validated for simultaneous determination of epimeric budesonide (BUD) and fluticasone propionate (FP) i

A theory of cohesive crack model is proposed to study crack interaction. The elastic behavior of the structure is represented by the influence functions, and the model is cast as integral equations. When there is more than one crack, the behavior of

The results of an experimental study of a sudden change in loading rate on the fracture behavior of normal- and high-strength concrete specimens of three different sizes are reported. Geometrically similar three-point bend specimens were subjected to

T he conceptual differences between the conventional cohesive crack model and the cohesive crack model discussed in this paper are briefly reviewed. Based on the potential energy principle and the assumption of a linear softening law, a boundary eige

The potential energy principle of the cohesive crack model is discussed under the condition that the loading device has finite compliance. The relation between crack instability and the second-order variance of the potential energy is examined. With
