Shearing equipment panels

Most mechanical tests developed for fats are empirical in nature and are usually designed for quality control purposes, and they attempt to simulate consumer sensory perception (3, 4). These large-deformation tests measure hardness-related parameters, which are then compared with textural attributes evaluated by a sensory panel (3, 5). These tests include penetrometry using cone, pin, cylinder and several other geometries (3, 6-12), compression (13), extrusion (13, 14), spreadability (15, 16), texture profile analysis (2), shear tests (13), and sectility measurements (14). These methods are usually simple and rapid, and they require relatively inexpensive equipment (3, 4, 17). The majority of these tests are based on the breakdown of structure and usually yield single-parameter measurements such as hardness, yield stress, and spreadability, among others (4, 17-20). The relationship between these mechanical tests and the structure of a fat has, however, not been established. The ultimate aim of any materials science endeavor is to examine the relationship between structure and macroscopic properties. 

Summarizing, it is possible to propose a design proeedure for this new aluminum-steel dissipater in the range of shear forees 0-150 kN. At design of the stmcture, the teehnieian must ehoose the most appropriate panel to be ineluded in the structure. The choice must be made based on the shear force expected for the panel, once it is inserted into the stmcture. Therefore, the size ofthe foree must be assessed by a numerical model of a stmeture without dissipaters but equipped with the same braces that will be utilized to install the deviees. 

The test frame had been equipped with numerous displacement and acceleration transducers. In particular, the displacements at the base level and at the first and second floors were measured. Moreover, a displacement transducer was positioned in order to measure the transversal displacement of each dissipating device. Finally, acceleration in transversal and longitudinal directions was measured at the first and at the second floors (Diaferio et al. 2010). Due to the geometrical configurations of the panel and of the frame, it was not possible to moimt a load cell to measure the transversal shear load acting on each panel.
