this paper investigates the effect of different methods of carbon nanotubes distribution in a thin matrix on static and dynamic behavior of the nanocomposite. five different symmetric patterns of distribution are considered, including four parabolic patterns and a linear one. for each pattern, the effective mechanical properties of the resultant nanocomposite are calculated using the rule of mi...
in this paper a new isolating system is introduced for short to mid-rise buildings. in comparison to conventional systems such as lrb and hrb, the proposed system has the advantage of no need to cutting edge technology and has low manufacturing cost. this system is made up of two orthogonal pairs of pillow-shaped rollers that are located between flat bed and plates. by using this system in two ...
background and aim of study: long span is seen in many clinical situations, treatment planning options of these cases are difficult and may require: fpd, rpd or isp. each option has its own disadvantages: mechanical, patient relief and cost respectively. this article will evaluate the stress distribution of another treatment option which is adding a single supporting implant to the fpd by using...
development of new technologies and combined with creativity and innovation, plays the fundamental role in developing of any community′s value. thus, in this research the design and production of hydroforming device was introduced. one of the best and most efficient technologies in the world of metal forming is wind turbine blade producing with hydroforming method which seems as an innovative m...
light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...
the use of structural adhesives in automotive structures has been increased recently for their role in noise, vibration and harshness (nvh). therefore, the dynamic behavior of structures containing bonded joints has become an area with numerous investigations over the past decades. development of accurate formulations capable of representing adhesively bonded joint dynamics is a step forward in...
in this paper, first design and analysis history of full metal cng cylinders for vehicle are investigated. next with respect to the cng worldwide standards, a full metal type cylinder is designed and analysed. then the numerical analysis results and practical results are compared, and the correctness of the investigation is verified. in the end, the most suitable alloy with respect to the dimen...
the finite element method (fem) is one of advanced methods in modeling of solid mechanics used in the design and analyzing of prosthesis in the human body. one of the important factors in designing a femur (the linkage between basin and knee) which is under complicated stresses is to minimize the amount of the stress in the components of the prosthesis due to the body weight. in this research t...
background: the salvage proximal femoral osteotomy is performed in mild or moderate osteoarthritis when the articulating surfaces are normal and relieves the subject’s pain. because the importance of angular mal-alignment of the femur bone at the hip junction accurate pre-op planning based on patient specific anatomy is required to prevent any lower limb misalignment and joint problem pre-opera...
the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...
