Ratcheting–Fatigue Damage Assessment of Additively Manufactured SS304L and AlSi10Mg Samples under Asymmetric Stress Cycles
نویسندگان
چکیده
The present study aims to investigate the interaction of ratcheting and fatigue phenomena for additively manufactured (AM) samples SS304L AlSi10Mg undergoing uniaxial asymmetric stress cycles. Overall damage was accumulated through on AM prepared from three-dimensional-printed plates along vertical horizontal directions. Fatigue evaluated based strain energy density approach calculated use an isotropic–kinematic hardening framework. isotropic description Lee–Zavrel (L–Z) model formed initial concentric expansion yield surfaces while Ahmadzadeh–Varvani (A–V) kinematic rule translated into deviatoric space. Ratcheting simulated using finite element analysis triangular quadrilateral elements. values were basis Chaboche’s materials model. predicted curves placed above experimental fatigue–ratcheting data collapsed below measured values. overall formulated partition weights due phenomena.

Additively Manufactured Porous Biomaterials and Implants
Recent advances in additive manufacturing (AM) techniques (otherwise known as 3D printing) have enabled fabrication of a new class of porous biomaterials (Figure 1) with arbitrarily complex and precisely controlled topologies that e.g. resemble the geometry and micro-architecture of (trabecular) bone. Since the geometry of scaffolds and biomaterials is an important factor in bone tissue regener...
متن کاملMechanical Properties of Additively Manufactured Thick Honeycombs
Honeycombs resemble the structure of a number of natural and biological materials such as cancellous bone, wood, and cork. Thick honeycomb could be also used for energy absorption applications. Moreover, studying the mechanical behavior of honeycombs under in-plane loading could help understanding the mechanical behavior of more complex 3D tessellated structures such as porous biomaterials. In ...

Additive manufacturing/3D printing of medical devices is becoming more commonplace, a 3D printed drug is now commercially available, and bioprinting is poised to transition from laboratory to market. Despite the variety of technologies enabling these products, the US Food and Drug Administration (FDA) is charged with protecting and promoting the public health by ensuring these products are safe...
متن کاملAdditively Manufactured Pneumatically Driven Skin Electrodes
Telemedicine focuses on improving the quality of health care, particularly in out-of-hospital settings. One of the most important applications is the continuous remote monitoring of vital parameters. Long-term monitoring of biopotentials requires skin-electrodes. State-of-the-art electrodes such as Ag/AgCl wet electrodes lead, especially during long-term application, to complications, e.g., ski...
متن کاملAdditively manufactured sub-periosteal jaw implants.
Severe bone atrophy jeopardizes the success of endosseous implants. This technical note aims to present the innovative concept of additively manufactured sub-periosteal jaw implants (AMSJIs). Digital datasets of the patient's jaws and wax trial in occlusion are used to segment the bone and dental arches, for the design of a sub-periosteal frame and abutments in the optimal location related to t...
