A Two-Dimensional Model for Pin-Load Distribution and Failure Analysis of Composite Bolted Joints.

Multibolt composite joints are widely used in aircraft structures. The determination of the pin-load distribution among the bolts is a critical step in the failure prediction of bolted joints. In this paper, a two-dimensional model of the multibolt composite structure is established for the pin-load distribution analysis.

Hot Deformation Behavior of a New Al-Mn-Sc Alloy.

The hot deformation behavior of a new Al-Mn-Sc alloy was investigated by hot compression conducted at temperatures from 330 to 490 °C and strain rates from 0.01 to 10 s. The hot deformation behavior and microstructure of the alloy were significantly affected by the deformation temperatures and strain rates.
