Modeling of a Stress-Strain State of Detachable Connection in Details of Reinforced Composite Materials with Cea Method

Abstract

In order to study the strength of the proposed rope threaded joint for machine parts made of reinforced composite materials, a modeling of a stress-strain state was conducted using the software of finite-element analysis LS-DYNA. Stress-strain state modeling was conducted for a rope threaded joint, affecting on the main performance parameters considered to be p – thread pitch (p = 4 mm), and t – thread depth (t = 1 mm). The main thread parameters taken for the model were up to the metric thread М6 (ISO 724:1993) parameters.

A Novel Semi-Analytical Approach to the Assessment of the Equivalent Stiffness of a Beam

“…A number of calculation methods have been developed only for certain specific composite lay-ups, e.g. the symmetrical composite lay-up described in [6], [20]. Users of these theories must be highlyqualified in the field of composite material mechanics so as to be able to select the appropriate calculation approach for a specific composite beam.…”

Mechanical Fatigue Test of Aluminium Composite Panel (ACP) with Aramid Nida-Core Under Cyclic Bending

“…Many papers were devoted to the fatigue behaviour of reinforced composite materials [10][11][12], under different loading conditions, with different types of glass fibre and surface modified alumina reinforced AZ91E magnesium based composites. A modelling of a stressstrain state of a detachable threaded joint with a rope thread was conducted.…”
