This item is printed on demand - it takes 3-4 days longer - Neuware -For nearly all workpieces made of steel a surface heat treatment to raise the hardness and the wear resistance is indispensable.A classic method for the heat treatment is induction hardening, where the heating is done by electromagnetic fields. Due to the induced eddy currents and the skin effect, the necessary heat to produce the high temperature phase austenite is generated directly in the workpiece. During the subsequent quenching, martensite forms in the boundary layer, which is characterized by its high hardness. The recently developed concept of multifrequency induction hardening uses two superimposed alternating currents with different frequencies to generate a hardening profile following the contour. This method is well suited to harden complex shaped workpieces such as gears, where the coupling distance to the inductor varies.The determination of optimal process parameters requires a lot of experience and validation by time-consuming and costly experiments. Therefore, there is a huge demand for numerical simulations of multifrequency induction hardening.The present work describes the modelling and the simulation of inductive heating of workpieces made of steel using the multifrequency concept. The model consists of a coupled system of partial and ordinary differential equations to determine the temperature distribution in the workpiece, the electromagnetic fields as the source of the Joule heat and the distribution of the high temperature phase austenite, which provides information about the resulting hardening pattern. Nonlinearities resulting from temperature dependent material parameters and a magnetic permeability that depends on the magnetic field itself are of great importance for the performance of the simulation.The coupled PDE-system is solved by the finite element method, whereby the electromagnetic subproblem is discretized by curl-conforming edge elements. Since due to the skin effect, the boundary layer of the workpiece must be resolved very accurately, the grid is generated adaptively using residual based error estimators. 136 pp. Englisch.…

Right of withdrawal
If you are a consumer you can withdraw from the contract in accordance with the following. Consumer means any natural person who is acting for purposes which are outside his trade, business, craft or profession.
Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to BuchWeltWeit Ludwig Meier e.K., Bergisch Gladbach, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
