"Mechanical design engineering Handbook is a straight-talking and forward-thinking reference covering the design, specification, selection, use and integration of machine elements fundamental to a wide range of engineering applications.Develop or refresh your mechanical design skills in the areas of bearings, shafts, gears, seals, belts and chains, clutches and brakes, springs, fasteners, pneumatics and hydraulics, amongst other core mechanical elements, and dip in for principles, data and calculations as needed to inform and evaluate your on-the-job decisions.Covering the full spectrum of common mechanical and machine components that act as building blocks in the design of mechanical devices, Mechanical Design Engineering Handbook also includes worked design scenarios and essential background on design methodology to help you get started with a problem and repeat selection processes with successful results time and time again."

"Di era modern ini, material komposit telah banyak digunakan dalam berbagai keperluan industri, termasuk otomotif, aviasi, hingga kebutuhan struktural. Penggunaan material komposit dinilai memiliki beberapa keuntungan dibandingkan dengan material konvensional seperti logam dan kayu, terutama karena sifatnya yang memiliki nilai strength to weight ratio yang tinggi, tahan terhadap temperatur tinggi, dan sifatnya yang bisa dimodifikasi sesuai dengan kebutuhan. Salah satu kelemahan dari material komposit adalah rendahnya ketahanan material terhadap beban impak yang relatif besar, terlebih lagi jika pembebanan impak tersebut dilakukan secara berulang untuk jumlah siklus yang cukup banyak. Saat ini belum ada standar, baik untuk prosedur maupun rancangan alat uji, yang membahas tentang pengujian impak dan fatik secara sekaligus untuk suatu spesimen material komposit. Oleh karena itu, perancangan alat uji impak dan fatik dalam kecepatan rendah dilakukan untuk memperoleh energi impak dalam jangkauan 1 hingga 10 Joule dengan jumlah siklus sebanyak 12000 siklus setiap satu jam. Dari perhitungan perancangan sistem linear, diperoleh besar kecepatan impaktor saat menumbuk material harus mencapai 1,87 m/s, yang bisa diperoleh dengan radius crank throw sebesar 110 mm.

In this modern era, composite materials are oftenly used for a lot of industrial needs, including automotive, aviation, and structural. Composite materials are used for their advantages instead of using conventional materials, such as steel ana wood, mainly because of their mechanical properties having high strength-to-weight ratio, high temperature resistance, and modifiable for any different needs. Composite materials have one considerable weakness, they have low resistance to relatively high impact loads. Moreover, a cyclic impact load for a long duration would have worse effect to the material. There are no standards for both testing procedures and testing machine design for composite material based impact and fatigue testing in a single machine. For that reason, an impact-fatigue testing machine is designed to provide impact energy in a range of 1 to 10 Joules with 12000 cycles every hour. From design calculation of the linear system, the impactor needs to collide with the specimen in 1,87 m/s velocity, which can be produced with a 110-mm crank throw radius."

"This book presents the proceedings of the 14th International Conference on Computer Aided Engineering, collecting the best papers from the event, which was held in Wrocław, Poland in June 2018. It includes contributions from researchers in computer engineering addressing the applied science and development of the industry and offering up-to-date information on the development of the key technologies in technology transfer. It is divided into the following thematic sections:- parametric and concurrent design,- advanced numerical simulations of physical systems,- integration of CAD/CAE systems for machine design,- presentation of professional CAD and CAE systems,- presentation of the modern methods of machine testing,- presentation of practical CAD/CAM/CAE applications:- designing and manufacturing of machines and technical systems,- durability prediction, repairs and retrofitting of power equipment,- strength and thermodynamic analyses of power equipment,- design and calculation of various types of load-carrying structures,- numerical methods of dimensioning materials handling and long-distance transport equipment (cranes, gantries, automotive, rail, air, space and other special vehicles and earth-moving machinery),- CAE integration problems."
