PURPOSE Interference fit fixation of soft-tissue grafts has recently raised strong interest because it allows for anatomic graft fixation that may increase knee stability and graft isometry. Although clinical data show promising results, no data exist on how tendon healing progresses using this fixation. The purpose of the present study was to investigate anterior cruciate ligament (ACL) recons...

A tapered interference fit provides a mechanically reliable retention mechanism for the implant-abutment interface in a dental implant. Understanding the mechanical properties of the tapered interface with or without a screw at the bottom has been the subject of a considerable amount of studies involving experiments and finite element (FE) analysis. In this paper, approximate closed-form formul...

When an expert designer uses a term such as “interference fit" or “H7r6", they effortlessly invoke a rich set of associations across a wide range of experience. While at one level, the meaning of a termsuch as H7 is formally specified, many of these associations are implicitand hard to characterize formally. The explicit concepts build on layersof implicit abstraction; e.g. the concept of _t wo...

The interference-fit size has a significant effect on the riveted lap joints of CFRP/Al alloy laminates. requirements for are different because strengthening heterogeneous materials. However, in riveting process alloys, laminates lead to poor structural strength requirements. Therefore, differently assembled molds designed acquire novel size, and tensile test is adopted evaluate their propertie...
