TL;DR: In this article, a constitutive model considering the strain-rate and temperature effects was presented by fitting the true stress-strain curves of Ti-6Al-4V alloy over a wide range of strain-rates (0.0005 −0.05 s −1 ) and temperatures (923 −1023 k).

TL;DR: In this article, an experimental study on the effect of bolt-hole clearance and bolt torque on single-lap, single-bolt, countersunk composite joints was presented, where the specimens were manufactured from carbon fiber/epoxy unitapes with quasi-isotropic lay-ups.

TL;DR: In this article, an experimental study on the effect of joining interface condition (including shimming and interface gap) on bearing response of single-lap, countersunk composite-aluminum bolted joints is presented.

TL;DR: In this paper, three promising multistage two-point incremental sheet forming (MTPIF) path strategies, i.e., parallel line strategy, variable angle strategy, and stretch-bend-assisted strategy, are selected to investigate the influence of tool paths on thickness distributions, material flow, and geometric error.

TL;DR: In this paper, a coupled thermomechanical finite element (FE) model considering the effect of heat transfer was established, and the influence of preheating temperature of die, initial temperature of extrusion, and dwell time on spring-back was researched based on orthogonal array testing strategy (OATS).
