The Fracture Characteristic of Three Collinear Cracks under True Triaxial Compression
The mechanical behavior of multicracks under compression has become a very important project in the field of fracture mechanics and rock mechanics. In this paper, experimental and numerical studies on the fracture property of three collinear cracks under compression were implemented. The specimens were a square concrete plate, and the cracks were made by a very thin film. The tests were conduct...
متن کاملDevelopment and Validation of Successful Aging Instrument
Objectives: Successful aging is an interdisciplinary concept. Despite the great body of literature on successful aging, few studies have focused on its subjective and multidimensional measurements. Thus, the present study aimed to develop an instrument to measure self-perceived successful aging. Methods: We used a mixed method approach. The successful aging dimensions were explored through an ...
متن کاملDevelopment and Validation of an Instrument to Evaluate English Language Teachers' Lesson Planning Self-concept
This study aimed to develop and validate an instrument to evaluate English language teachers’ lesson plan- ning self-concept. To this end, 30 English teachers were asked to prepare a sample lesson plan and 15 of them were invited to participate in a semi-structured interview. A tentative questionnaire including six fac- tors namely: classroom management, lesson planning conformity, planning eff...
متن کاملWriting Self-Efficacy Instrument: Development and Validation
Self-efficacy is an important trait that factors into a teacher’s ability to effectively teach writing. Teacher’s self-efficacy in writing, however, has been widely ignored by the writing research community. This study developed a new instrument to measure a teachers’ writing self-efficacy and examined its psychometric properties. The Writing Self-Efficacy Instrument demonstrated factorial scor...
متن کاملInvestigation of Stress-Strain Behavior of Plastic Concrete Using Monotonic Triaxial Compression Tests
In this paper, the mechanical behavior of plastic concrete being used in the cut-off walls of earth dams has been studied. To do the task, triaxial compression tests on the specimens in various ages and mix designs under different confining pressures have been done and the stress-strain behavior of such materials and their strength parameter changes has been experimentally investigated. It has ...
