cracked and un-cracked brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (pc) material. the value of mode i fracture toughness (kic) was determined from the center- cracked brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked brazilian disc specimen. the...
BACKGROUND The purpose of this study was to analyze the characteristics of cracked teeth and to evaluate pulp status according to periodontal probing depth (PPD). METHODS A total of 182 cracked teeth were included. The location and type of the cracked teeth, age and gender of the patients, restoration type, pulp status, PPD, and radiographic findings were analyzed. RESULTS Mandibular second...
Purpose – The purpose of this work is to describe the effects of the length of cracks and the patch size on the stress intensity factors in a bonded composite repair structure containing multiple site damage. Design/methodology/approach – Finite element method was applied to simulate a bonded repair of a cracked aluminum plate with multiple site damage. A two-dimensional three-layer technique w...
is much more complicated and leads to slowly convergent or even divergent expressions for the stress resultants. 2 The circular support's action on the plate is equivalent to a line load, and so the discontinuity in the elastic constants certainly make the deflection function singular at r = a. This is reflected in the fact that two different expressions are needed to describe the deflection fu...
In Eurocode 3, a design rule is given for predicting the ultimate resistance of net cross-section at bolt holes. This based on average stress evaluated in cross-section, and contains both reduction factor 0.9 partial factor. According to previous research, this makes over-conservative uncracked components. There are indications that conservatism accounts possible presence small cracks Very limi...
This paper proposes a new method using Wide Line Detector based statistical shape Feature (WLDF) to identify whether or not a tongue is cracked; a cracked tongue is one of the most frequently used visible features for diagnosis in traditional Chinese Medicine (TCM). We first detected a wide line in the tongue image, and then extracted WLDF, such as the maximum length of each detected region, an...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
An anisotropic model of damage mechanics for ductile fracture incorporating the endochronic theory of plasticity is presented in order to take into account material deterioration during plastic deformation. An alternative form of endochronic (internal time) theory which is actually an elasto-plastic damage theory with isotropicnonlinear kinematic hardening is developed for ease of numerical com...
