R - curve modeling of rate and size effects in quasibrittle fracture
The equivalent linear elastic fracture model based 0:;': an R-curve (a curve characterizing the variation of the critical energy release rate 'WIth the crack propagation length; IS generalized to describe both the rate effect and size effect observed in concrete. rock or other quasi brittle matenals. It is assumed that the crack propagation velocity depends on the ratio of the stress intensity ...
متن کاملScaling theory for quasibrittle structural failure.
This inaugural article has a twofold purpose: (i) to present a simpler and more general justification of the fundamental scaling laws of quasibrittle fracture, bridging the asymptotic behaviors of plasticity, linear elastic fracture mechanics, and Weibull statistical theory of brittle failure, and (ii) to give a broad but succinct overview of various applications and ramifications covering many...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
Size-Effect Testing of Cohesive Fracture Parameters and Nonuniqueness of Work-of-Fracture Method
The cohesive crack model has been widely accepted as the best compromise for the analysis of fracture of concrete and other quasibrittle materials. The softening stress-separation law of this model is now believed to be best described as a bilinear curve characterized by four parameters: the initial and total fracture energies Gf and GF , the tensile strength f 0t , and the knee-point ordinate ...
متن کاملLeptgenesis from Bilinear R-parity Violating Couplings
We reexamine the idea that bilinear R-parity violating couplings can be responsible for leptogenesis. We prove that, to have lepton number violation before the electroweak phase transition, misalignment between the lepton-Higgsino and slepton-Higgs sectors must be involved. The processes that generate a lepton asymmetry are bino or wino decays into a lepton-Higgs and slepton-Higgsino final stat...
