Bi-Stability in Flexure Beams: Introducing a Setup for Experimental Characterization
نویسندگان
چکیده
Bi-stable mechanisms can remain in two positions without a power input or locking system. These achieve large displacements with low energy, requiring only during switching. However, their design and analysis are challenging due to the non-linear behavior of flexible members. Researchers commonly use experimental approaches study validate bi-stability, which demands efficient affordable setups. This work presents versatile easy-to-fabricate setup investigate bi-stable flexure beams made styrene plastic. The testing is laser-cut acrylic connectors 3D-printed fixtures. experiments demonstrate that all tested highlight impact thickness on behavior. critical forces obtained range from 0.0277 N 5.2724 between thinnest thickest samples. distance traveled before snapping increments, thickness, ranges 18.78 mm 32.6 mm. samples were subjected cyclic compressive load demonstrated considerable decrement after first load. Thicker flexural present more significant deformation, causing fractures some cases five loads. Regardless same total linear displacement 45 presented consistency rapidness bi-stability characterization, plastic proving be suitable for studying bi-stability.

Experimental Study on Full-Scale Beams Made by Reinforced Alkali Activated Concrete Undergoing Flexure
Alkali Activated Concrete (AAC) is an alternative kind of concrete that uses fly ash as a total replacement of Portland cement. Fly ash combined with alkaline solution and cured at high temperature reacts to form a binder. Four point bending tests on two full scale beams made with AAC are described in this paper. Companion small material specimens were also casted with the aim of properly chara...
متن کاملA Multi-objective Immune System for a New Bi-objective Permutation Flowshop Problem with Sequence-dependent Setup Times
We present a new mathematical model for a permutation flowshop scheduling problem with sequence-dependent setup times considering minimization of two objectives, namely makespan and weighted mean total earliness/tardiness. Only small-sized problems with up to 20 jobs can be solved by the proposed integer programming approach. Thus, an effective multi-objective immune system (MOIS) is ...

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Longitudinal Phase Space Setup for the SLC Beams
The longitudinal phase space distribution of the SLC beams is affected by many different machine parameters and constraints. By using a technique of over-compression [1] in the ring to linac transfer line, a small energy spread of 0.12 % can be achieved at the end of the linac for a bunch length of 1.2 mm (σ). In the final focus a small energy spread is desirable to reduce emittance dilution du...
