Optimum design of composite structures with curved fiber courses
TL;DR: In this paper, a new methodology for the optimum design of laminated composites with curved fiber courses is presented, where the objective of the optimization problem is to minimize the weight of the composite laminate under stress constraints.

A comparison of stress and strain distribution characteristics of two different rigid implant designs for distal-extension fixed prostheses.
TL;DR: The results indicated that the ITI 1 (hollow screw) implant led to high stress concentrations particularly in the apical region, while the stress-transferring characteristics of ITI 2 (solid screw) implants were found to be more suitable than were those of ITi 1.

A natural tooth's stress distribution in occlusion with a dental implant.
I. Akpinar,N. Anil,Levend Parnas +2 more
TL;DR: This study investigated stresses formed around the implant and the antagonist natural tooth under occlusal force in the substitution of a missing lower first molar with a rigid or resilient IMZ (Intra Mobil Zylinder) implant, using the finite element stress analysis method.

- 01 Jan 1991
TL;DR: In this paper, a study was conducted to analyze tapered composite laminates under tensile loading and the principle of minimum complementary potential energy was used to determine interlaminar stresses.

Resin infusion under flexible tooling process and structural design optimization of the complex composite part
TL;DR: In this paper, an automotive body part with glass woven fabric/epoxy composite manufactured by RIFT Type I (RIFT I) process is investigated both experimentally and numerically to improve the mechanical characteristics with weight saving.
