Panel Shear of Plywood in Structural Sizes - Assessment Improvement Using Digital Image Correlation
نویسندگان
چکیده
This paper introduces a new test configuration for the determination of panel shear properties in structural sizes. original has been successfully applied to calculate beech plywood. A numerical model developed evaluate influence such novel setup comparison common standard. The research includes mechanical characterization total 36 samples using Digital Image Correlation (DIC) measure plane displacements. use DIC proven be efficient and also acts as tool ensure that solicitation was adequate during test. Finally, results highlight interest actually perform proposed instead alternative density-based equivalencies provided by standards.

assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Image Matching Error Assessment in Digital Image Correlation
Using concepts from statistics and probability theory and a least squares matching metric, the effects of various parameters on image plane motion measurements are demonstrated. Specifically, theoretical formulae defining the effect of noise in the intensity pattern, image contrast and interpolation method on both bias and variability in one-dimensional motion measurements are presented. Image ...
متن کاملDisplacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)
There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...
متن کاملStress Field Analysis of V-Notches with Tip Cracks in a Polymer Material Using Digital Image Correlation
In this study, displacement field around v-notches of a poly methyl metha crylate (PMMA) specimen with tip cracks will be analyzed using digital image correlation technique. First intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...
