Electric Vehicles Are Redefining Modern Transportation. As the Global Fleet Surpasses 57 Million Units, Battery Safety Has Become a Critical Engineering Priority. A Single Lateral Impact Can Compress Battery Modules Beyond 20 MPa. Above That Threshold, Internal Short Circuits and Thermal Runaway Begin. This Thesis Attacks the Problem at Its Structural Root. It Presents the First Systematic Study of DP980 High-Strength Steel Paired with Unidirectional Carbon Fibre-Reinforced Polymer as a Hybrid Bottom Shell for EV Battery Packs under Lateral Bar Impact. Two Laminate Topologies Are Examined. In the SC-Type, DP980 Forms the Outer Layer. In the CS-Type, CFRP Takes the Outer Position and DP980 Serves as the Inner Liner.The Research Is Built on 258 Abaqus/Explicit Finite Element Simulations Across Five Impact Velocities and Two Impact Positions, Generated by Latin Hypercube Sampling. Eight Machine Learning Surrogate Models Are Trained on This Dataset. The MPA-SVR Architecture Emerges as the Top Performer. It Achieves an R? of.9941 for Energy Absorption and.9980 for Peak Deformation. Three Multi-Criteria Decision Methods Converge Unanimously on the Same Answer. TOPSIS, Grey Relational Analysis, and Hybrid GRA-TOPSIS All Select the CS-Type as the Primary Optimal Design. Its Specification Is a 1.5 mm CFRP Outer Layer Paired with a.6 mm DP980 Inner Liner. Against the Monolithic DP980 Baseline, This Delivers a 10.94% Gain in Specific Energy Absorption, a 3.69% Reduction in Deformation, and an 11.82% Reduction in Structural Mass. Two Independent Loading Scenarios Confirm the Result. Sprache: Englisch Gewicht in Gramm: 234.…

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 Home-set, Mannheim, 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.
