Hi all, I am currently working on a lifting beam which has to be designed/analysed in accordance with BS13155:2020. In the past, I have designed lifting beams which were based upon the clients own safety factor requirements and manuals, therefore BS13155 wasnt used as such. The following is...

Hi all, I am currently working on a problem which involves exposing a bolted joint to an increase in temperature (delta 250 C). In the past I have dealt with typical pretorqued bolt joints (ambient temperature) where the required pretorque was approximated by working out the actual required...

Hello, I would appreciate it if someone could give me advice regarding constraint requirements in sol101 contact body analysis. So I have a rectangular plate clamped around its edges. An unconstrained cylinder is pushing down on it using a force card. Contact bodies have been defined. Is that...

Hello, I am currently working on a fixture which is essentially a beam with upward forces being applied at both its ends. The centre of the beam reacts the total load via a threaded bar which is grounded at its base. The previous derivative of the fixture required that the threaded bar be...

Hello All, Question 1: I have a general question regarding the units consistency for linear static runs. I have always been told to use consistent units i.e. in my case its typically N, mm, MPa, tonne, tonne/mm^3,mm/s^2. I always stick to these units but could someone tell me if kg (mass)...

Hello all, I am looking at a setup which includes a simply supported pipe with another pipe of same length slotted inside it.Assuming no friction exists between the two pipes, Am I correct to assume that the two pipe sections do not act as one whole section with a combined second moment of area...

Hello all, I created a simple FE model representing a basic lap joint with the two surfaces of equal thickness (represnted by shells) modelled 3mm apart to simulate eccentricity. i have idealised the fasteners as bar elements. however, i cant understand why one end of the bar element(s) is...

Hi everyone, I am currently working on a repair job which is as follows: the part being repaired resembles an L shaped bracket which attaches to the parent structure via fasteners. fatigue issues have arisen due to undesirable design features, and therefore straps on both sides of this joint...
